Definitions
- the present invention relates generally to removal of paints and sealants and more particularly to non-destructive and efficient apparatuses and methods for such removal.
- Scraping is usually accomplished with either a putty knife or a paint scraper, or both.
- Putty knives range in width from one to six inches and have a beveled edge.
- a putty knife is used in a pushing motion going under the paint and working from an area of loose paint toward the edge where the paint is still firmly adhered.
- Paint scrapers are commonly available in 1-5/16, 2-1/2, and 3-1/2 inch widths and have replaceable blades.
- profiled scrapers can be made specifically for a particular purpose.
- a paint scraper is used in a pulling motion and works by raking the damaged areas of paint away.
- Scrapers may be formed from steel, aluminum, wood, Mycarta, and nylon, the desired choice being a softer material than the substrate being scraped to avoid marring for appearance or structural reasons.
- thermal methods such as an electric heat plate and electric heat gun. Thermal methods have limited applications.
- Solvent-base strippers have formulas that generally contain combinations of organic solvents such as methylene chloride, isopropanol, toluol, xylol, and methanol. Thickeners such as methyl cellulose and various additives such as paraffin wax are added to prevent the volatile solvents from evaporating before they have time to soak through multiple layers of paint. Some solvent-base strippers are quite thin and therefore unsuitable for use on vertical surfaces while others, called “semi-paste" strippers, are formulated for use on vertical surfaces or the underside of horizontal surfaces. More recently, paint removers have been formulated using a mixture of water and benzyl alcohol.
- a paint removal system that addresses some of the above-noted problems is desirable.
- the present invention provides a cost-effective and minimally destructive apparatus and method for removing paint and other coatings from a surface.
- the present invention provides an apparatus for removing a substance from a surface.
- the apparatus comprises a tape having a masking material adapted to adhere to the surface and a stripper, wherein applying the masking material and the stripper can be performed in a single step.
- the apparatus comprises a matrix impregnated with the stripper and a bladder in which the stripper is impregnated.
- the matrix and bladder are disposed centrally with respect to a lengthwise axis of the tape and the masking material is disposed on lateral sides of the tape.
- a backing material is removably adhered to the tape.
- the apparatus comprises an elongated tape having the masking material disposed along lateral sides thereof and the stripper disposed between the masking material.
- the tape is wound on a roll and includes a removable backing.
- the present invention provides a method of removing a substance from a surface.
- the method comprises masking a portion of the surface with masking material to protect it from a stripper and applying the stripper to an unmasked portion of the surface. These steps are performed at substantially the same time.
- One advantage of the present invention is that it saves time.
- the stripper and masking material can be applied at the same time, in a single step, as opposed to two separate steps.
- Use of this invention allows airplane operators to perform the removal step within their maintenance hangers during other routine checks, rather than requiring the aircraft to be dispatched to a specialized facility for removal of paint and sealant.
- the invention is envisioned as being supplied to the user as a complete kit required for whatever model of aircraft is being examined for scribe marks. Current practice is to mask the aircraft as though it were being completely stripped of paint and sealant. This invention can eliminate that labor intensive step in the process.
- Another advantage of the present invention is that it allows less stripper to be used because the stripper material, which is typically volatile, is covered, which greatly reduces evaporation. Less stripper is used, saving material costs and also reducing the amount of waste and thus reducing disposal costs. Efficiency of the stripper improves, since the solvent that penetrates the paint is being held next to the surface in the channel, rather than evaporating into the atmosphere. In addition to increased efficiency, the reduction in evaporation will mean less contribution from the stripper to total VOC output of the facility, thereby providing considerable pollution prevention advantages.
- the present invention will significantly reduce the "cleanup" phase of the stripping operation, where considerable amounts of solvent and contaminated water waste are generated. Since the paint and sealant adhere to the fiberglass mesh matrix at the conclusion of stripping, all of the contributors to pollution, viz., stripper, paint and sealant, will be confined to one item that may be disposed of accordingly.
- Another advantage of the present invention is that, since only the stripper and mesh pad are in contact with the surface being examined, no adhesive residues are left that might interfere with the inspection process

- apparatus 10 for removing a substance from a surface is provided as a tape 12 having masking material provided as strips 14.
- a stripper segment or matrix 16 is provided in the center of tape 12, between strips 14.
- Stripper segment 16 further includes a fibrous material layer 18.
- bladder 20 Adjacent to and in contact with fibrous layer 18 is bladder 20, which in the illustrated embodiment includes a liquid stripper that, during use of apparatus 10 as explained below, will impregnate or saturate fiber layer 18 with a liquid chemical stripper (not shown).
- Bladder 20 is preferably configured to rupture upon the application of a force to it such that the liquid therein saturates layer 18, as explained below.
- Neoprene is one suitable material for bladder 20.
- a rectangular shell 22 forms a channel and houses therein layer 18 and bladder 20.
- Shell 22 is preferably made of a quasi-rigid material such as Mylar ® .
- Optional beads 24 join masking material 14 to shell 22.
- the beads 24 may be made of rubber or other suitable polymer.
- a removable backing 26 covers tape 12 as shown. Tape 12 is wound on a roll 28.
- masking material 14 is preferably provided as a conventional masking tape having an adhesive 30 applied on one side thereof.
- One tape suitable for use with apparatus 10 is an aluminum adhesive tape meeting MIL-T- 23397B, one (1) inch wide, available from 3M Coiporation, Grade 417 Aluminum Foil Tape, 900 Bush Avenue, St Paul Minnesota, 55133.
- the adhesive provided on the tape should sufficiently adhere to the surface being stripped such that it forms a liquid-proof seal with the surface, thereby rendering bead 24 optional.
- masking material 14 is attached thereto by means of heat welding, sonic welding, adhesives or other suitable fastening means.
- Shell 22 is also joined to bead 24 by any of a variety of suitable fastening means. As alluded above, shell 22 is relatively rigid for the reasons described below. A suitable material for shell 22 meets MIL-P-22270 and is available from Dupont Discovery Films, 1 Discovery Drive, Hopewell Virginia, 23860. The approximate desired thickness for shell 22 is 10 mils.
- An alternative packaging material is an oxygen barrier bagging material, commonly known as "mylar" bags and consisting of a mylar/aluminum sandwich. For improved puncture resistance, nylon may be substituted for polyester. These products are manufactured by and available from IMPAK coiporation, 2460 East 57 th St, Los Angeles, CA 90058. Also, while shown as rectangular in the illustrated embodiment, shell 22 may have a curved or rounded profile. Shell 22 is preferably non-porous such that the stripper liquid contained therein cannot escape by leakage or evaporation.
- the liquid which fills bladder 20 can be any of a variety of commercially available strippers, depending upon the particular paint, sealant or coating that is to be removed with the stripper.
- the stripper should be capable of removing both a polyurethane topcoat, epoxy primer and common polysulfide sealants, such as sealants meeting MIL-S-8802.
- One such stripper is Eldorado Solutions, PR-3133, Eldorado Solutions, Carmel Indiana.
- Fibrous materials suitable for layer 18 can be any material that is inert to the stripper and that tends to spread the stripper material evenly over the surface contacted upon contact.
- the term "inert” is intended to mean that the fibrous material does not substantially chemically react with the stripper composition and is capable of maintaining mechanical integrity for a period at least as long as the shelf life of apparatus 10.
- suitable materials for fibrous layer 18 include polymers, such as polypropylene and polyethylene; woven and non-woven fabrics, such as felts, cotton and wool; and glass fibers such as fiberglass.
- One of skill in the art would readily recognized many materials that would perform suitably for fibrous layer 18.
- Backing 30 may be polyvinyl chloride (PVC), nylon, paper with a metallized interior to prevent chemical migration, mylar with aluminized backing, or any other material having the following characteristics: ability to form into a channel for insertion of bladder and fibrous matrix; rigid, yet deformable that can be crushed with a nylon hand scrapper; chemically resistant to migration of the stripper for sufficient time (e.g., less than 24 hours); and compatible with the other materials used for apparatus 10, such as the adhesive on the aluminum tape.
- PVC polyvinyl chloride
- nylon nylon
- mylar with aluminized backing or any other material having the following characteristics: ability to form into a channel for insertion of bladder and fibrous matrix; rigid, yet deformable that can be crushed with a nylon hand scrapper; chemically resistant to migration of the stripper for sufficient time (e.g., less than 24 hours); and compatible with the other materials used for apparatus 10, such as the adhesive on the aluminum tape.
- tape 12 is applied to a surface such as aircraft skin 34, particularly, over lap joint 36.
- Most aircraft have many lap joints such as joint 36 having rivets 38 securing the joints.
- Sealant as well as paint is typically applied to the joints.
- the paint and sealant must first be stripped from the joints.
- metal scrapers that are commonly used tend to gouge or "score" the aircraft skin, which may ultimately cause larger cracks.
- Tape 12 is centered over the lap joint desired to be stripped and then applied to the skin 34 in the same manner as a conventional piece of tape. After the tape is applied, pressure is applied as indicated by arrows 40 to shell 22, which ruptures the bladder, which in turn causes the liquid stripper to saturate the fibrous layer 18. The fibrous layer then meters the stripper fluid, i.e., spreads it evenly over the surface of the skin desired to be stripped. Beads 24 prevent the stripper fluid from spreading laterally and thus define a border or periphery beyond which the stripper does not reach.
- tape 12 is removed from aircraft skin 34.
- the stripper has caused the paint and sealant to delaminate from the aircraft skin and stick to fibrous layer 18, but otherwise remain intact.
- the paint and sealant are removed as a single layer along with tape 12.
- this will not be possible, in which event manual wiping and perhaps some light scraping after removal of tape 12 is required to remove the residual paint and/or sealant.
- the masking material and stripper are applied at substantially the same time, in a single step.
- apparatus 100 having a backing 102, a circular fibrous layer 104, and a masking material 106 surrounding the fibrous layer.
- Apparatus 100 can be used for stripping spots of a surface at desired locations. Apparatus 100 is simply applied to the spot desired to be stripped in a manner similar to that described above with reference to apparatus 10.
- Fig. 4 illustrates another embodiment in which apparatus 200 includes stripping areas 202 that are evenly spaced for use in applications where the areas desired to be stripped are also evenly spaced.
- the underside of apparatus 200 (not shown) includes a liquid stripper material that is preferably contained in a bladder and/or fibrous material, and also includes a removable backing layer as described above.
- apparatus 300 includes a tape 302, a backing material 304 and a liquid stripper- impregnated fibrous matrix 306 sandwiched therebetween.
- the optional bladder is not provided in this embodiment. Instead, the backing material 304 and tape 302 form a liquid impervious seal 308 which maintains the stripper material within fibrous matrix 306 until the backing material is removed and apparatus 300 is applied to a surface desired to be stripped.
- FIG. 6 illustrates an embodiment in which apparatus 400 includes a tape 402 and a shell 404, both of which are joined to beads 406.
- a backing material 408 is hermetically sealed to tape 402.
- a bladder 410 is housed in shell 404 and contains the liquid stripper.
- Apparatus 400 is applied in the same fashion as apparatus 10, except there is no fibrous matrix provided in apparatus 400. Beads 406 help prevent liquid stripper from spreading laterally outside of the area intended to be stripped.
- the apparatus comprises a fiberglass mat 18 adjacent to a Tygon ® bladder 20 filled with stripper.
- Bladder 20 in turn is surrounded by a PVC channel or shell 22 which has been secured to aluminum tape 14 flanking the channel with another layer of tape 14a. That is, unlike the embodiment in Fig. 1 that has a single tape 14, this embodiment includes two tape layers 14, 14a laminated together.
- the contents of the PVC channel 22 are protected from weather by a removable paper backing (not shown).
- the adhesive pull strength of the upper layer of tape 14a is about one half of the tape 14 adhering to the desired surface, thus allowing the operator to remove the channel 22, stripper bladder 20 and mesh matrix 18 while leaving the outer tape masking 14 adhered to the surface. Since chemical removal of paint and sealant may not be complete, this embodiment allows the user to do minor "touchup" work prior to removing layer 14 and performing the inspections noted above.
