摘要： A polyester-based coating composition capable of forming a striated pattern on a metal surface at a film thickness less than half of that of PVC plastisol films is provided by a thixotropic composition having a thix index of from about 1.5 to about 3 and comprising a hydroxy-functional polyester, a thixotropy-inducing rheologic agent and curing agent. The striated coating is applied to sheet metal in a coil coating operation by introducing the composition into a paint pan of a coil coater, transferring said composition from said paint pan to an applicator roll by rotating a pick-up roll in contact with the composition and with said applicator roll; continuously withdrawing a sheet of metal from a coil thereof and coating said sheet by contacting it with the applicator roll; curing the coating on said sheet by passing the sheet through an oven at an elevated temperature; and continuously rewinding said sheet into a coil.

摘要： Pigmented, abrasion and corrosion resistant, thermosetting organic solvent solution coating composition comprise: (A) from about 50 percent to about 85 percent of total resin solids of a triol-based blocked polyurethane polyisocyanate having a number average molecular weight in the range of 600 to 4000; (B) from about 15 percent to about 50 percent of total resin solids of an epoxy-phosphate provided by reacting a resinous polyepoxide with at least 0.05 mole of orthophosphoric acid per equivalent of oxirane in the polyepoxide; and (C) a corrosion-inhibiting pigment, preferably a chromium-containing pigment, providing resistance to corrosion. These coatings may be applied to the metal surface to be protected, or the metal surface may be protected with another primer which is overcoated with the subject coatings. The subject coatings are then topcoated, especially with pigmented fluorocarbon coatings.

The carboxyl-functional polymer preferably comprises a copolymer formed by polymerization in aqueous dispersion of the monomers in solution in an appropriate polyhydric alcohol. The pigment is preferably suspended in a carboxyl-functional resin which dissolves in water with the aid of a base. The preferred soluble resin is a copolymer with an oleyl alcohol ether of a polyepoxide and the preferred pigment is barium chromate.
