Abstract:
A non-aqueous coating composition comprising:(A) 50 to 80 weight percent, based on total resin solids of (A) and (B), of an acrylic polyol comprising the polymerization product of:(i) 20 to 70 percent hydroxy functional acrylate monomers comprising:(a) 0.5 to 15 percent of acrylate or methacrylate in which the esterifying group is the residue of a glycidyl group and includes a branched alkyl group;(b) 5 to 40 percent of acrylate or methacrylate in which the esterifyinig group is a hydroxy ester having one or more ester groups; and(c) 0 to 40 percent of one or more hydroxyalkyl acrylate or hydroxyalkyl methacrylate monomers different from (a) or (b);(ii) 30 to 80 percent acrylate monomers without functional groups reactive with isocyanate; and(iii) 0 to 5 percent unsaturated acid monomer;wherein the percentages of each of the acrylic polyol constituents is based upon total resin solids weight of all the acrylic polyol constituents;(B) 20 to 50 weight percent, based on total resin solids of (A) and (B), of a curing agent reactive with hydroxyl groups;the percentages based on weight of total resin solids of the composition; and(C) diluent consisting essentially of organic liquid;wherein the volatile organic content of the coating composition is less than 4.0 pounds per gallon in a non-aqueous composition.
