Abstract:
A powder coating composition comprising: (i) a substantially non-gelled polymeric composition that is the reaction product of an A polymer which is an addition polymer having 3.5 or more reactive functional groups per polymer chain and a B polymer having about 2 to about 3 functional groups per polymer chain that are co-reactive with said reactive functional groups of the A polymer; (ii) optionally a cross-linking agent; (iii) optionally a colorant; and (iv) optionally an epoxy resin, wherein substantially all of the co-reactive functional groups of the B polymer have been co-reacted and a molar ratio of A polymer to B polymer is about 3:1 to about 2:1.7.
