Abstract:
A priming agent composition useful for binding a layer containing a fluorocarbon polymeric material to a metallic or an organic polymeric substrate, said composition comprising:about 98 to 99.99 weight percent of a crosslinked, glycidyl end-capped bisphenolic polymer having the formula ##STR6## wherein R.sup.1 and R.sup.2 are each independently H or an alkyl group containing 1 to about 4 carbon atoms, R.sup.3 and R.sup.4 are each independently H, F, or an alkyl group containing 1 to about 4 carbon atoms, Z is a carbonyl cross-linking group, x is an integer from 1 to about 10; andabout 0.01 to 2 weight percent of a perfluoroalkylsubstituted glycidyl-reactive compound having the formula ##STR7## wherein R.sup.5 is H or F, Q is SiR.sup.6 R.sup.7 R.sup.8, and R.sup.6, R.sup.7, and R.sup.8 are each being independently selected from the group consisting of Cl, OH, an alkyl group containing 1 to about 4 carbon atoms, an alkoxy group containing 1 to about 4 carbon atoms, an acyloxy group containing 2 to about 4 carbon atoms, and an amino group containing 0 to about 4 carbon atoms; and n is an integer from 1 to about 15; with the proviso that at least one of said R.sup.6, R.sup.7, and R.sup.8 is Cl, OH, or an alkoxy, acyloxy, or amino group.
