SUNOX® EXTREME Plastic Adhesion Promoter Aerosol 500ml
SUNOX® EXTREME Plastic Adhesion Promoter Aerosol 500ml
Professional Plastic Primer – Maximum Adhesion on Automotive Plastics
SUNOX® EXTREME Plastic Adhesion Promoter is a specialist clear primer designed to maximise paint adhesion on automotive plastics and other difficult-to-coat substrates. Developed for professional refinishing applications, it creates a transparent bonding layer that helps primers, basecoats and topcoats adhere securely to plastic surfaces.
Modern plastics can be difficult to paint due to their low surface energy and the presence of mould release agents. SUNOX EXTREME Plastic Adhesion Promoter helps overcome these challenges, significantly reducing the risk of peeling, flaking and coating failure.
Its fast-drying clear formula allows rapid overcoating, making it an essential product for plastic bumper repairs, trim refinishing and general automotive plastic painting.
