Abstract:
A coating composition comprises a first copolymer and a second copolymer. The first copolymer has at least one linear polymer strand having a weight average molecular weight of at least 1,500 Daltons and functionality X with an equivalent weight of no more than 500. The second copolymer has at least one linear polymer strand having a weight average molecular weight of at least 1,500 Daltons and functionality X′ with an equivalent weight of no more than 1,500. The coating composition is free of gloss flattening agents, yet still produces a cured film having a low gloss of less than 70 gloss units at an angle of incidence of 60°, as measured according to ASTM D 2457.
