Definitions
- the flakes be able to reflect light back to the viewer, and this is the reason why large flakes (long dimension greater than the coating thickness) are used. Small flakes are insufficiently reflective to give a distinct difference in appearance between the area of reoriented flakes and planar disposed flakes, or in other words to give a distinct pattern in the coating.
- the reoriented flakes may protrude from the surface of the coating, while the flakes which lie in the plane of the coating, i.e., not tilted, will generally not protrude from the surface of the release coating. Even though some of the reoriented flakes protrude from the surface of the release coating, the protruded portions of such flakes are coated with the composition of the release coating to form "mounds" of release coating encasing the protruding portions of the flakes. The profile of these mounds, tapering into the flat surface of the coating, enable the coating (after baking) to serve as a release coating.
- the pattern is decorative.
- the pattern can be present on the cooking (baking) surface and give the appearance of being three dimensional even though the release coating on the substrate is smooth.
- the release coating is smooth, the smooth surface characterized by a surface roughness of less than 1.5 micrometers.
- the pattern is in the form of liquid level indicia in the sidewall of the release-coated vessel. This sidewall marking information is provided by the magnetic reorientation of the flakes without any embossing of the cookware or bakeware sidewall and with the coating containing the magnetically reoriented flakes being sufficiently smooth surfaced to still serve as a release coating.
- the magnetic force is applied to form the pattern as further shown in Figure 1.
- the magnetizable die 12 is made of sheet metal, e.g., 0.1 mm to 4 mm thick, and is in the form of a morningstar pattern as best shown in Figure 2.
- the sheet metal forming the die 12 is at an angle with respect to the plane of the underside of the fry pan 2. so that the upper edge and not the face (side) of the sheet metal forms the pattern of localized magnetic force in the coating 8.
- the upper edge of the sheet metal can be as thin as a knife edge as well as thicker, e.g., up to the 4 mm thickness mentioned above.
- the die 12 in essence looks like a cookie cutter, with its size depending on the size of the pattern to be formed in the release coating.
- the interior space 14 of the die can be filled in by nonmagnetizable solid material such as wood (not shown).
- the magnetizable die is not the source of the magnetic force.
- the source of the magnetic force is magnet 16 which can be a permanent magnet or as shown in Figure 1 can be an electromagnet having a central pole 18 surrounded by electrical coil 20 and in turn by an annular pole 21.
- the magnet 16 generates the magnetic force necessary for the invention.
- the magnet 16 is spaced from the frying pan 2, and the magnetic force from the magnet is communicated to the release coating through the die 12.
- the spacing of the magnet from the underside of the substrate can be great enough that the coating on the substrate is not directly exposed to the magnetic force of the magnet or the magnetic force of the magnet 16 is diffused into a magnetizable metal plate 22 interposed between the magnet 16 and die 12.
- the micas described in these patents are coated with oxides or hydrous oxides of titanium, zirconium, aluminum, zinc, antimony, tin, iron, copper, nickel, cobalt, chromium, or vanadium. Titanium dioxide coated mica is preferred because of its availability. Mixtures of coated micas can also be used. The mica or coated mica is ordinarily present in the topcoat at a concentration of about 0.2-20% by dry weight of the composition.
- the primer composition used in the present invention in aqueous dispersion form may also contain such other additives as adhesion promoters, such as colloidal silica or a phosphate compound, such as a metal phosphate, e.g., Zn, Mn, or Fe phosphate.
- adhesion promoters such as colloidal silica or a phosphate compound, such as a metal phosphate, e.g., Zn, Mn, or Fe phosphate.
- minute fissues in the midcoat provide easy pathways for moisture to permeate through all the layers to reach the substrate (frying pan) and cause blistering of the coatings.
- the polyamic acid salt coverts to polyamideimide and bonds the flakes to the fluoropolymer.
- the midcoat obtained in this Example is free of minute fissures.
