Abstract
Methods of providing substrates with a durable coating comprises applying a pigmented composition of fluorocarbon resin and acrylic resin to the substrate followed by application of a clear composition of flurocarbon resin and acrylic resin. Articles produced by the methods are especially useful wherever outdoor exposure is encountered.
Claims16
A method of providing a durable coated substrate, comprising the steps of:
- (a) applying a pigmented coating composition to a substrate, said composition consisting essentially of from about 45% to about 85% of a fluorocarbon resin and from 15% to about 55% of a thermoplastic acrylic resin, on a resin solids basis, and having a PVC of from about 3% to about 55%, on a dry film basis;
- and
- (b) applying a clear coating composition to the coated substrate of step (a), said composition consisting essentially of from about 45% to about 85% of a fluorocarbon resin, and from about 15% to about 55% of a thermoplastic acrylic resin, on a resin solids basis;
- and
- (c) baking the coated substrate of step (b) to cause the coatings to fuse together intimately in a bonding process to provide good intercoat adhesion and craze-resistance, thereby forming the coated substrate.
