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 pol
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 epoxide, anhydride, isocyanate, silane, acid hydroxy, amide or any combination of these groups; and about 70-95% by weight, based on the weight of the macromonomer, of at least one other polymerized ethylenically unsaturated monomer without a crosslinking functionality; and(c) about 5-25% by weight, of a crosslinking agent of tris(alkoxy carbonyl amino) triazine.
