This invention relates to a coating composition comprising (A) 100 weight parts of at least one epoxy resin; (B) 40 to 900 weight parts of at least one alkoxy-containing aminofunctional silicone resin; (C) up to 50 weight parts of at least one organic hardener; (D) up to 100 weight parts of at least one epoxyfunctional silicone resin; and (E) up to 10 weight parts of at least one cure accelerator, provided the alkoxy-containing aminofunctional silicone resin (B) has a total alkoxy content ranging from 26 to 80 mol percent per mole of silicon (Si) in the alkoxy-containing aminofunctional silicone resin. Methods for preparing the above-described composition and for treating substrates are also disclosed.
