Abstract
A low temperature cure coating system exhibiting high performance characteristics, particularly solvent resistance and impact resistance, which is capable of being applied to either metal or plastic substrates. Dissimilar topcoat and basecoat compositions are employed, the topcoat being an aqueous polymeric dispersion, acid catalyzable for curing at temperatures of 150.degree. F. and below while the basecoat is selected for compatibility with the topcoat and the substrate, either the metal or plastic, to give proper adhesion, flexibility, film integrity and lack of interference with topcoat performance.
