High solids coating composition of an acrylic polymer a polyester polyol and an alkylated melamine crosslinking agent

摘要

The high solids coating composition contains at least 40% by weight of a binder of film-forming constituents in which the constituents are of (1) an acrylic polymer of styrene or methyl methacrylate or mixtures thereof, an alkyl acrylate or an alkyl methacrylate and a hydroxyl alkyl acrylate or methacrylate (2) a polyester polyol and (3) an alkylated melamine formaldehyde crosslinking agent and optionally, an acid catalyst; the composition is particularly useful as a primer or an exterior finish for automobiles, trucks, airplanes and can be used as an appliance finish and for coil coatings.
