Polymeric coating compositions, polymer coated substrates, and methods of making and using the same

摘要

This invention relates to a coated substrate comprising (i) a substrate and (ii) a coating thereupon comprising a polymeric composition formed from (a) twenty-five to ninety-nine parts by weight of a poly(amide-imide) prepolymer; (b) one to twenty-five parts by weight of a trifunctional ester selected from the group consisting of trifunctional methacrylate ester, trifunctional acrylate ester, and mixtures thereof; (c) from 0.5 to fifteen parts by weight of an organo-reactive silane consisting of an amino group containing alkoxysilane having the formula NH2(CH2)nSi(OC2H5)3 where n is an integer from one to twenty; and (d) a conductive additive.
