Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

C08L 2712
C08L 2716

US Classification:

525199

Abstract:

A coating composition useful for providing a substrate with a coating having a textured appearance is composed of, on a resin solids basis, a resinous mixture of: (a) from about 40 percent to about 85 percent by weight of a film-forming fluorocarbon resin having a particle size of from about 0. 1 microns to about 5 microns; (b) from 0 percent to about 50 percent by weight of an acrylic resin selected from polymers and copolymers of acrylic acid or methacrylic acid esters and copolymers of acrylic monomers containing hydroxyl or amide groups; and (c) from about 3 percent to about 50 percent by weight of particulate fluorocarbon resin having a particle size ranging from about 20 microns to about 3500 microns, said particulate fluorocarbon resin being fused with the film-forming fluorocarbon resin upon curing to provide said textured appearance. The aforesaid coating composition can be either a clear or pigment coating composition.
