Abstract
A silicone release polyester film coated with an aqueous silicone coating composition on one surface. The aqueous silicone release coating composition is made up of an alkylvinylpolysiloxane containing vinyl groups, a tin or platinum catalyst, a glycidoxysilane and an alkylhydrogenpolysiloxane. A process for coating a polyester film with the aqueous silicone coating composition is also disclosed, where the coating occurs in-line, disclosing the manufacturing process for the film before it is heat-set. The silicone release coated polyester film has an acceptable release value when subjected to solvents or heat.
