SILANE TREATMENT FOR ELECTROCOATED METALS

摘要

A method of treating a metal substrate by applying a coating of a silane solution comprising at least one bis-silyl aminosilane which has been at least partially hydrolyzed and at least one bis-silyl polysulfur silane which has been at least partially hydrolyzed. The silane coating provides corrosion resistance, as well as improved adhesion to electrocoats and other polymers. A silane coated metal substrate, as well as a silane solution, are also provided.
