Abstract
The present invention provides a multi-layer coating system, comprising a first coating composition and a second coating composition, wherein the first coating composition comprises an acrylic resin (a) having a glass transformation temperature (Tg) of at least 70° C. and the second coating composition comprises a three-functionality polyester acrylate, a six-functionality polyurethane acrylate, and a nine-functionality polyurethane acrylate. The present invention further provides a method of coating a multi-layer coating system on a substrate and a substrate coated with the multi-layer coating system.
Claims12
A multi-layer coating system, comprising a first coating composition and a second coating composition, wherein the first coating composition comprises an acrylic resin (a) having a glass transformation temperature (Tg) of at least 70° C. and the second coating composition comprises a three-functionality polyester acrylate, a six-functionality polyurethane acrylate, and a nine-functionality polyurethane acrylate.
A method of forming a multi-layer coating system on a substrate, comprising:
- (1) applying a first coating composition to at least a portion of the substrate, to form a base coat;
- and
- (2) applying a second coating composition to at least a portion of the base coat, to form a clear coat,
- wherein the first coating composition comprises an acrylic resin (a) having a glass transformation temperature (Tg) of at least 70° C. and the second coating composition comprises a three-functionality polyester acrylate, a six-functionality polyurethane acrylate, and a nine-functionality polyurethane acrylate.
A coated substrate, comprising:
- (i) a substrate, and
- (ii) a multi-layer coating system deposited on at least a portion of the substrate, the multi-layer coating system comprising a first coating composition and a second coating composition, wherein the first coating composition comprises an acrylic resin (a) having a glass transformation temperature (Tg) of at least 70° C. and the second coating composition comprises a three-functionality polyester acrylate, a six-functionality polyurethane acrylate, and a nine-functionality polyurethane acrylate.
