The visibility and/or optical clarity of all or any portion or portions of the headlamp cover 600 can be improved by applying a permanent or semi-permanent very thin or thin glass structure 100A according to the specific examples described herein. Structure 100A can be replaced if necessary by applying heat to remove structure 100A and then replacing it with another structure. It has been found that if the headlamp cover or other display device has a composite curve (i.e., a curve involving multiple radii), the disclosed thin and very thin specific examples can easily conform to this composite curvature due to the very thin or very thin glass substrate. The essence of thinness. That is, the thinner the glass piece or substrate, the more suitable it is to conform to the composite curve. In other embodiments, the glass structure can be laminated or ion exchanged to strengthen the glass to help form a composite curve. In still further embodiments, the glass structure can be scratched in selected portions thereof to ensure compliance of the structure with the composite curve. For example, in some embodiments (see FIGS. 11A and 11B), the example glass structure 1100 can be controlled to pry open (ie, not rupture) to one or more scribe lines 1110 while remaining bonded to the polymer (ie, The polymer is not cut, cleaved, or broken, thereby allowing the overall structure to be "tiled" and adjustable to accommodate complex curvature. It should be noted that although the scribe lines 1110 are depicted as being linear and/or orthogonal to one another (eg, in the x and y directions, see, for example, FIG. 11A), the scope of the accompanying claims should not be so limited due to the scribe line 1110 can be produced in any direction and in any pattern (curve scribe lines, parabolic scribe lines, hyperbolic scribe lines, star scribe lines, and the like, see, for example, Figure 11B) to conform the example glass structure 1100 to the underside Complex curvature included on the surface.

These include solid adhesive resins, liquid adhesives (also known as plasticizers), antioxidants, fillers, pigments, waxes, and the like. The adhesive material may contain a mixture of a solid adhesive resin and a liquid adhesive resin (or a liquid plasticizer). Exemplary additives are also disclosed in U.S. Patent Nos. 5,192,612 and 5,346,766, each incorporated by reference. Exemplary temporary or semi-permanent adhesives include the ability to remove a sample laminate or composite structure and to reattach or apply a sample laminate or composite structure to a surface, to an article, and to other structures. Exemplary permanent adhesives can be removed using heat treatment, UV exposure, or the like. Generally, the use of a binder type is a function of the application of the specific examples described herein.

Additional useful pressure sensitive adhesives include those that remain on the exposed surface, after being imprinted, backed or padded with a microstructure forming tool, or coated onto a microstructure forming tool, After the backing or liner, the pressure sensitive adhesive is subsequently removed. The particular pressure sensitive adhesive selected for a given application is dependent upon the type of substrate to which the laminate or composite structure described herein is applied, and the microstructure method is utilized to prepare the adhesive backing structure. In addition, useful microstructured pressure sensitive adhesives should be capable of maintaining their microstructured surface for a time sufficient to permit the use of the adhesive backing structure.

The choice of binder is usually based on the type of substrate to which it is attached. Additional types of pressure sensitive adhesives include acrylic, adhesive rubber, adhesive synthetic rubber, vinyl vinyl acrylic, anthrone, and the like. Suitable acrylic adhesives are disclosed, for example, in U.S. Patent Nos. 3,239,478; 3,935,338; 5,169,727; RE 24,906; 4,952,650; and 4,181,752.

Exemplary binders can also be polymers dispersed in a solvent or water and applied to the release liner and dried, and optionally crosslinked. If a solvent-borne or water-borne pressure-sensitive adhesive composition is utilized, the adhesive layer should be subjected to a drying step to remove all or most of the carrier liquid. An additional coating step can be necessary to achieve a smooth surface. The example binder can also be hot melt coated onto a liner or microstructure backing. Additionally, the monomer pre-bond composition can be applied to a liner and polymerized with an energy source (eg, heat, UV radiation, electron beam radiation).

The thickness of the adhesive depends on several factors including, for example, the composition of the adhesive, the type of substrate used to form the microstructured surface, the type of substrate, and the thickness of the film. Those skilled in the art will be able to adjust the thickness to accommodate a particular application factor. Typically, the thickness of the adhesive layer is greater than the height of the structure comprising the microstructured surface. In some embodiments, the thickness of the adhesive layer is in the range of from about 2 to about 50 [mu]m, from about 2 to about 100 [mu]m, or from about 10 to about 500 [mu]m, and all subranges therebetween.

Other example binders may optionally include one or more binders. Depending on the polymerization method, coating method, end use, and the like, it may be selected from the group consisting of a starter, a filler, a plasticizer, an adhesive, a chain transfer agent, a fiber reinforcement, a woven or a non-woven fabric, An additive comprising a group of foaming agents, antioxidants, stabilizers, flame retardants, viscosity enhancers, colorants, and mixtures of the foregoing.

In one embodiment, an adhesive can be applied by adhering a removable adhesive laminate to the release liner or carrier layer. In some embodiments, the adhesive member can also comprise a release liner as described in Figures 5A-5F. Exemplary release liners include polyethylene coated paper with an anthrone release coating, polyethylene terephthalate coated film with an anthrone release coating, or cast polypropylene film when these films are fabricated It can be embossed in a pattern or in multiple patterns and then coated with an anthrone release coating. The release liner can be selected based on its release properties relative to the pressure sensitive adhesive selected for use in a particular embodiment. In some embodiments, the surface of the release liner can have a texturing process, a smoothing process, or a patterning process. The release layer can have a random microstructured surface, such as a matte finish or a pattern that can have a three-dimensional microstructure. The microstructure may have a cross-section that is formed by a circle, an ellipse, a diamond, a square, a rectangle, a triangle, a polygon, a line, or an irregular shape when the section is parallel to the surface of the release surface.

In other embodiments, the second surface of the example adhesive layer can have a Sheffield roughness of at least about 10, or at least about 75, or at least about 150. The second surface of the adhesive layer may itself have a marked roughness or may form a rough surface when the adhesive is applied to the release liner. It will be appreciated that the surface of the release liner may have a Sheffield roughness of at least about 10 or at least about 50, or at least about 75 or at least about 150. The adhesive typically replicates the complementary texture or pattern of the release liner. Alternatively, the release liner can be rougher depending on the configuration of the adhesive member.

method

Referring to Figures 1-5 and 10, one or more edges of the depicted structure may be the result of a cutting process that uses at least one of the following techniques: shearing, burst cutting, razor cutting, Crush cutting, scratch cutting, and rotary die cutting. The nature of the laminate or composite structure in these figures is such that one or more of the resulting edges from the cut structure exhibit very fine, particle-free properties, few defects, and/or edge angle defects. In particular, there is no need to utilize complex and expensive laser cutting techniques to cut structures. The desired edge properties are such that any lateral cracks due to the cutting operation and penetration into the glass sheet by the cutting edge are no greater than: (i) about 1400 microns; (ii) about 1000 microns; (iii) about 800 microns; (iv ) about 600 microns; (v) about 400 microns; (vi) about 200 microns; (vii) about 100 microns, and (viii) about 50 microns. It has been discovered that shearing the laminate or composite structure described herein with a scissor-type cutting mechanism produces high quality cutting edges, particularly when a polymer layer or adhesive is used in the structure, due to the lateral cracking caused by the cutting operation by the cutting The edge enters the glass sheet to penetrate no more than about 600 microns. It has also been found that lateral cracks created by performing the same cutting technique on a sample glass sheet without a polymer layer penetrates from the cutting edge into the glass sheet by about 1600 microns. In some experiments, when attempting shearing, samples without polymer layers caused cracks in the glass sheet and broke into many pieces. In additional experiments, it was discovered that the rotary die cutting mechanism for the laminate or composite structure described herein also produced high quality cutting edges. Several samples of varying thickness, including 100 micron, 50 micron, 25 micron, and 10 micron, each with a 3 mil (PET-heat sealable PET) polymer layer (bonded to glass to form a glass-polymer laminate) It is cut using a rotary die cutter. The sample is approximately 20 cm x 20 cm (length x width). During the experiment, the 10 micron thick sample exhibited edge properties such that the lateral crack caused by the cutting operation penetrated from the cutting edge into the glass sheet by no more than about 84 microns. In a 100 micron thick sample, the edge properties of a similar experimental performance were that the lateral crack caused by the cutting operation penetrated from the cutting edge into the glass sheet by no more than about 380 microns. Surface analysis of all samples showed a significant difference from the lateral crack and surface extent along the edge, depending on the thickness of the glass sheet, such that a thinner 10 micron sample exhibited less and less laterality than a thicker sample crack. Thus, it has been found that in addition to the above-described improvement in the nature of the cutting edge, the use of a polymer layer in the glass sheet provides some additional features to the laminate structure. For example, a suitable material selection to form a glass sheet and polymer layer can provide a very desirable water vapor transmission rate (WVTR). WVTR measures the airtightness or impermeability of the barrier film to water vapor. The thin and very thin glass and polymer structures described herein provide glass-like impermeability that is superior to commercially available individual plastic film barriers. Based on available literature, glass WVTR is cited as less than about 10 ^-6 g.mm/m ² .day. The existing quantitative side results show that the glass actually exhibits about ⁶ x ^{10 -6} g.mm/m ² .day; however, such values are actually due to the limits of current measuring equipment, rather than the actual vapor barrier properties of the glass. It can in fact be above this measurement limit. The glass and polymer laminate structures described herein can thus have a WVTR value similar to glass. In contrast, a commercially available polymer film high barrier performance of many separate the WVTR, such as PET of 0.39-0.51 g.mm/m ² days; the polycarbonate 3.82-4.33 g.mm/m ^2. Day; and nylon 6 of 15–16 g.mm/m ² .day.

Furthermore, by laminating thin or very thin glass with one or more polymer layers, the polymer increases spatial stability (especially a plane substantially perpendicular to the thickness direction) due to the barrier properties of the glass, while being thin and extremely thin Glass adds greater flexibility and is similar to the flexibility of plastic materials. The increased stability may be in one or more of the following forms: latent resistance, reduced elasticity and elongation at break, reduced moisture permeability, coefficient of thermal expansion (CTE) of the laminate, or post-forming crystallization. The glass and polymer laminate structure further provides easy handling and handling compared to flat thin glass, whether it is a sheet or mesh placed on a roller.

Referring to Table 1 below, the exemplary composition of the glass sheets according to some specific examples was varied during the experiment to evaluate the effect on the edge properties of the laminate or composite structure. For example, changes in the molar percentage of SiO ₂ , Al ₂ O ₃ , B ₂ O ₃ , MgO, CaO, SrO, BaO, and ZnO are produced on several samples. Table 1

From the results of the experiment and referring to Table 2 below, it was found that acceptable edge properties existed in the example specific example including the composition of the glass sheet from the molar percentage of about 50-80% SiO ₂ , 2-15% Al ₂ O ₃ , 10–36% B ₂ O ₃ , 1–15% RO (where RO is one or more of MgO, CaO, SrO, BaO, ZnO), and 0–5% of other minor components. Although the composition above is found to be very effective, it is believed that other components of the glass will produce satisfactory (although somewhat different) results, depending on the particular application. Table 2

Additional example laminate or composite structures may include commercially available glass including, for example, EAGLE XG ^® , Lotus ^TM , Willow ^® , Iris ^TM , and Gorilla ^® glass from Corning Incorporated. Some non-limiting glass composition may comprise between about 50 mol SiO percent to about 90 mol _2, at from about 0 mol% to about 20 mol Al ₂ O ₃ of between%, from about 0 mol% to about 20 B ₂ O ₃ between mol%, and R _x O between about 0 mol% and about 25 mol%, wherein R is any one or more of Li, Na, K, Rb, Cs and x 2, or R is any one or more of Zn, Mg, Ca, Sr, or Ba and x is 1.

In an additional specific embodiment, the laminate or composite structure may comprise between about 72 mol SiO%% to about 80 mol _2, about ₃ mol Al ₂ O 3% to between about 7 mol%, and from about 0 mol From about 2 mol% of B ₂ O ₃ , between about 0 mol% to about 2 mol% of Li ₂ O, between about 6 mol% to about 15 mol% of Na ₂ O, at about 0 mol% to about 2 mol% of K ₂ O, between about 0 mol% to about 2 mol% of ZnO, between about 2 mol% to about 10 mol% of MgO, at about 0 mol% Between about 2 mol% CaO, between about 0 mol% to about 2 mol% SrO, between about 0 mol% to about 2 mol% BaO, and between about 0 mol% to about 2 mol % between SnO ₂ . In some embodiments, the glass substrate may comprise from about 60 mol% to about 80 mol SiO ₂ between percent, from about 0 mol% to between about 15 mol% of Al ₂ O _3, from about 0 mol% Up to about 15 mol% of B ₂ O ₃ , and between about 2 mol% and about 50 mol% of R _x O, wherein R is any one or more of Li, Na, K, Rb, Cs And x is 2, or R is any one or more of Zn, Mg, Ca, Sr, or Ba and x is 1. In further embodiments, the laminate or composite structure may comprise a suitable soda lime glass or other float making glass.

Glass sheets in these example laminated or composite structures may also comprise glass that is chemically strengthened (eg, ion exchanged). During the ion exchange process, ions in or near the surface of the glass sheet are exchanged for larger metal ions, such as from a salt bath. The incorporation of larger ions into the glass strengthens the flakes by creating compressive stresses near the surface area. Corresponding tensile stresses can be induced in the central region of the glass sheet to balance the compressive stress. Ion exchange can be carried out, for example, by immersing the glass in a molten salt bath for a predetermined period of time. Examples include, but are not limited to salt bath _{KNO 3, LiNO 3, 3,} RbNO 3 , and the binding of NaNO. The temperature of the molten salt bath and the treatment time period can be varied. Depending on the desired application, those skilled in the art will be able to determine time and temperature. As a non-limiting example, the temperature of the molten salt bath may range from about 400 ° C to about 800 ° C, such as from about 400 ° C to about 500 ° C, and the predetermined time period may range from about 4 to 24 hours, for example From about 4 hours to about 10 hours, however other temperatures are contemplated to be combined with time. As a non-limiting example, the glass can be immersed in a KNO ₃ bath, for example at about 450 ° C for about 6 hours to obtain a K-rich layer that imparts surface compressive stress.

The process illustrated is a re-drawing process in which a web of glass sheet 702 material supplied by source drum 701 enters the oven and is heated to a re-drawing temperature. It may be necessary to remove the temporary electrostatic film (which may be pre-applied to the glass sheet 702 as a protective film) before placing the glass sheet 702 in the re-drying oven. Of course, such a temporary film can be applied by a pre-forming process to preserve the original glass quality prior to re-drawing. Antistatic strips can also be utilized at various points in the process to protect the initial surface of the glass sheet 702. The glass sheet 702 is then carefully stretched to a desired thickness (e.g., less than about 300 microns or other thicknesses as described above). One or more sources of polymer film 706 (eg, rollers or spools) 752, 754 and/or adhesive are provided downstream of the stretch zone and a polymer layer 706 is applied to the glass sheet 702 (which is due to the pull-down glass oven) The residual heat can be at a high temperature). The stacker 760 provides additional pressure, heat/cooling, tension, and the like to promote the desired bonding of the polymer layer 706 and/or the adhesive to the glass sheet 702 and to create a web 703 of the exemplary laminate structure.

The aforementioned cutting step (eg, via shearing, slitting, or the like) can be provided downstream of the laminate zone. A plurality of cutting elements 720 can be provided to create a plurality of strips of laminated material that are rolled onto a suitable number of finish spools 704A, 704B, 704C. When the edge of the mesh 703 is to be discarded, the cutting element 720 is positioned closer to the edge of the mesh 703, and while the spool 704B collects the desired strip for subsequent processing, the outer spools 704A, 704C may collect the discarded portion.

It should be noted that this illustration is merely an example, as there are any number of various methods to apply polymer layer 706 to glass sheet 702. For example, polymer layer 706 can be applied to glass sheet 702 from a spool, via a rigid mold, via spray coating techniques, and the like. Polymer layer 706 can also be bonded to glass sheet 702 via pressure, chemical techniques, thermal techniques, UV curing techniques, adhesive layers, and/or any combination of the above or other techniques known in the art or developed in the future. technology.

Additional and/or alternating continuous reeling apparatus 800 for cutting a laminate or composite structure is illustrated in Figures 8-9. It is noted that device 800 can be combined with certain structures of FIG. 7 to achieve further functionality, although those skilled in the art will recognize that there are certain common or at least similar structures in the separate devices of FIGS. 7 and 8-9. Apparatus 800 operates to cut web 803 of laminate structure into at least two strips 803A, 803B. Additional cuts may be provided to discard the obsolete portions of the edges 801A, 801B of the mesh 803. Typically, device 800 operates to supply the source of mesh 803 and continuously move mesh 803 from source to destination 804A, 804B (collectively "804") in a transport direction (indicated by an arrow) along the length of mesh 803. During the transport of the web 803 from the source to the end point 804, the web 803 is cut into at least first and second strips 803A, 803B at the cutting zone 847. The mesh 803 has a length (in the transport direction) and a width of the cross-cut length, and the respective widths of the first and second strips 803A, 803B are limited to the overall width of the mesh 803.

Web 803 can be provided by a wide range of sources. For example, a mesh 803 can be provided by using the aforementioned re-drawing forming apparatus (see FIG. 7) without a finish spool, ie, where the finished web 803 can be introduced into the transport mechanism of the apparatus 800 for cutting. Alternatively, the source of the mesh 803 can include a winding spool 802 as illustrated, wherein the mesh 803 is first wound onto the spool 802, for example, after the re-drawing process described above with reference to FIG. Typically, the winding spool 802 is provided with a diameter to exhibit acceptable bending stress to conform to the characteristics of the mesh 803. Once wound, the mesh 803 can be unwound from the spool 802 and introduced into the transport mechanism of the device 800. It is noted that the mesh 803 can generally include a pair of opposing edge portions 801A, 801B and a central portion 805 that spans between opposing edge portions 801A, 801B. Due to the re-drawing process (or other forming process), the edge portions 801A, 801B of the mesh 803 may have undesirable features, such as beads, which are typically greater than the thickness of the central portion 805 of the mesh 803. These features can be removed by using the cutting techniques described herein or other methods.

The end point of the device may include any suitable mechanism for accumulating the respective strips 803A, 803B. In the example shown in FIG. 9, end point 804 includes first and second spools 804A, 804B, each of which receives and winds one of strips 803A, 803B. Again, the spools 804A, 804B should be provided with suitable diameters to exhibit acceptable bend radii to conform to the features of the respective strips 803A, 803B.

Apparatus 800 includes a transport mechanism having a number of separate elements that cooperate to continuously move web 803 from source spool 802 in the transport direction to end spool 804. This conveying function can be accomplished without damaging the desired features of the edge portions 801A, 801B, the resulting edges from the cutting operation, or any (original) side of the central portion 805 of the mesh 803. In short, this transport function can be accomplished without compromising the desired characteristics of the individual strips 803A, 803B.

In particular, apparatus 800 can include a plurality of non-contact support members, rollers, and the like to guide web 803 and strips 803A, 803B from source spool 802 through the system to end spool 804. The example non-contact support members 806, 808 can be flat and/or curved to achieve the desired direction of transport of individual workpieces. Each of the non-contact support members 806, 808 can have a fluid bar and/or a low friction surface to ensure that the mesh 803 and strips 803A, 803B are properly transported through the system without damage or contamination. When a given non-contact support member 806, 808 includes a fluid strip, the element includes a plurality of channels and ports configured to provide a positive fluid pressure flow (eg, air), and/or a plurality of channels and ports, configured to A negative fluid pressure flow is provided to the associated surface of the mesh 803 and/or strips 803A, 803B to create an air cushion for this non-contact support. The combination of positive fluid pressure flow and negative fluid pressure flow stabilizes the mesh 803 and strips 803A, 803B during their transport through the system.

Alternatively, a number of lateral guides (not shown) may be utilized adjacent edge portions 801A, 801B and/or strips 803A, 803B of mesh 803 to assist in positioning mesh 803 on a desired side relative to the transport direction. To the location. For example, lateral guidance can be performed by using a roller that is configured to engage a corresponding one of the opposing edge portions 801A, 801B of the mesh 803, and/or one or more edge portions of the strips 803A, 803B. When the mesh 803 is transported through the device, the mesh 803 can be displaced and aligned for proper lateral positioning by correspondingly laterally guiding the opposing stresses applied to the edge portions 801A, 801B.

The apparatus 800 further includes a cutting mechanism 820 that operates to cut or separate the mesh 803 in the cutting zone 847 as the mesh 803 passes through, for example, the non-contact support member 808. The cutting mechanism 820 can make a single cut or a simultaneous multiple cut. In particular, however, the cutting mechanism 820 need not be a laser system to achieve the desired edge properties. Alternatively, the cutting mechanism can be of a less complex, lower cost type as described above, such as shearing, pulse cutting, razor cutting, stretch cutting, scratch cutting, slitting, and the like.

According to one or more further embodiments, one or more of the foregoing cutting techniques (e.g., shearing) can be combined with a scratch (or scribing) operation to achieve a desired result. As described above, when the example laminate structure is cut, the lateral cracks will begin at the cutting edge and propagate into the glass sheet 802. It has been found that some control of the propagation depth of these cracks can be obtained using scribing techniques. In particular, a scribing tool (e.g., a diamond tip tool) can be used to first scribe or scratch a groove in the glass sheet 802 parallel to and slightly away from an intended cutting line. Once the scribe line segments (which exhibit the groove-like properties in the surface of the glass sheet 802) are ready, a cutting operation is performed to cut along the intended cutting line. Any crack that propagates from the cutting edge toward the scribe line segment will stop propagating to the scribe line segment. Moreover, due to this groove, any crack that reaches the scribe line segment will suddenly change direction, where the direction of propagation changes from substantially across the thickness of the glass sheet 802 to substantially parallel to the thickness of the glass sheet 802. Thus, the placement of the scribe line segments relative to the intended cut line will give the skilled artisan some control over the extent of microcracks and thus control the quality properties of the cut edges.

The scribing technique described above has been found to be successfully applied to the shearing of scissors-type mechanisms (although other cutting techniques may also benefit). In particular, when the example laminate structure is cut with scissors, the cracks propagate from both sides of the cutting edge (caused by a single cut) and into the respective portions of the glass sheet 802. It has been found that these cracks propagate significantly further to a portion of the glass sheet 802 than another portion of the glass sheet 802, and this property is highly correlated with the sides of the scissors where the respective portions of the glass sheet 802 are cut. The period was located. In other words, the mechanical nature of the scissors does not cause symmetrical processing of the respective portions of the glass sheet 802 on the individual sides of a cut; instead, the action of the scissors actually manipulates a portion of the glass sheet 802 in such a manner that the crack is compared to other portions Further spread into this section. Without wishing to be bound by any theory of operation, it is believed that the particular mechanism of manipulating behavior is that the scissors bend the portion of the glass sheet 802 more heavily on one side of the scissors than the other portions of the glass sheet 802, thus The other part, causing more cracks on the side of the glass piece 802 on one side. The placement of the scribe line segments on one side of the intent to cut the line segment (i.e., on the side of the side of the intent to cut the line segment corresponding to the side of the scissors that tend to bend the glass sheet 802 more severely) mitigates the crack on the side edge. propagation.

The scribing technique described above can be applied to only one side of the intended line segment or can be applied to both sides of the intended line segment, all depending on the urgent needs of the particular application. The resulting edge of the example laminate structure that is cut using the scribe line segments will include an extreme cut edge, an intermediate region from the cut edge that is inwardly from the cut edge toward the scribe line segment, and substantially no cracks from the cutting operation. The entire area from the line segment to the inside. The resulting structure can be used in this state or further processed, for example, by removing the polymer layer 806 in the intermediate region and removing portions of the glass sheet 802 of the intermediate region (which contain cracks). Removal of portions of the glass sheet 802 in the intermediate region may include breaking the portion or providing mechanical emphasis such that the portion is detached from the example laminate structure. This manipulation causes a new edge to the line segment of the sample layer structure.

According to an alternative method, scribing techniques can be applied to the laminate structure without the use of subsequent cutting techniques. Moreover, a scribing tool can be used to scratch the polymeric layer 806 along the intent separation line segment and into the underlying glass sheet 802. However, without further cutting techniques (e.g., shearing), the structure can be broken along the scribe line segment (i.e., along the intended separation line segment) to achieve the desired cutting edge.

Adhesive layers as described herein can be applied to specific examples of various methods. In some embodiments, the adhesive layer can be sprayed onto the main surface of the laminate structure or a portion thereof (eg, edges, corners, etc.) using a nozzle having an air flow that can break the supplied adhesive into a Small droplets. The pattern presented by the droplets can be a function of the nozzle geometry, and the diameter of the spray pattern or cover is directly related to the distance between the nozzle and the substrate or laminate, and the adhesive droplets are directed toward the substrate or laminate. The size of the adhesive droplets can be varied by appropriately adjusting the air and adhesive supply pressure, and the coating weight applied to the moving substrate or laminate can be adjusted by varying the spray feed rate or the speed at which the substrate or laminate moves. Therefore, the application of the adhesive of the spray mechanism can provide great use for applying the coating. Other methods of applying the adhesive may include other spraying methods, printing, ink jet printing, roll printing, screen printing, or other known deposition methods.

The specific examples described herein thus provide a bonded thin or very thin glass platform, such as a separate (single) laminate structure with an adhesive on the surface of the individual structures.
