The high solids coating composition contains at least 50% by weight of a binder of film-forming constituents in which the constituents are of (A) an acrylic polymer that has a number average molecular weight of about 500-4,500, a hydroxyl content of at least 2% by weight, a glass transition temperature of about -20 DEG C. to +20 DEG C. and optionally contains a chain transfer agent, and is of an alkyl methacrylate, a hydroxy alkyl acrylate or a hydroxy alkyl methacrylate, and optionally, an alkyl acrylate or styrene (B) an alkylated melamine formaldehyde cross-linking agent; the composition is particularly useful as an exterior finish for automobiles, trucks, airplanes and can be used as an appliance finish and for coil coatings. |
