Polyvinyl butyral resin is used like on Vinilex 110 Active Primer that is based on butyral resin, anti corrosive (zinc chromate) pigment and phosphoric acid as a catalyst. It is a conventional etching primer in twin pack composition (base and catalyst) having good weather and solvent resistance. Adhesion to metal surfaces and subsequent paint, and anti - corrosion is good enough to be widely used as a wash primer of short exposure type for new plates pretreated in nonferrous metal, such as aluminum.
