Abstract
A coating composition containing about 40-90% by weight of film forming binder and 10-60% by weight of an organic liquid carrier;wherein the binder contains about(a) about 50-90% by weight of an acrylosilane polymer containing about 30-95% by weight based, based on the weight of the acrylosilane polymer, of polymerized monomers of styrene, alkyl (meth)acrylates having 1-12 carbon atoms in the alkyl group and hydroxy alkyl (meth)acrylates having 1-4 carbon atoms in the alkyl group and any mixtures thereof and 5-70% by weight, based on the weight of the polymer, of polymerized ethylenically unsaturated monomers containing reactive silane groups and the polymer has a weight average molecular weight of about 1,000-30,000;(b) about 5-25% by weight of a non-aqueous dispersed polymer of(i) a macromolecular core having a weight average molecular weight of about 50,000-500,000, and(ii) attached to the macromolecular core, a plurality of macromonomer chains having a weight average molecular weight of about 1,000-30,000 of 5-30% by weight, based on the weight of the macromonomer, of polymerized ethylenically unsaturated monomers which having functional groups selected from the following epoxi…
