The HIGH TECK ADHESION PROMOTER AEROSOL is a specialty coating designed to enhance paint and primer adhesion on difficult-to-bond substrates. This aerosol formulation provides consistent coverage and penetration on plastic surfaces and existing primer layers, creating a strong foundation for subsequent coating applications in collision repair work.
The product offers reliable performance when applied at the recommended temperature of 68°F, ensuring optimal chemical bonding between the promoter and substrate. Its aerosol delivery system enables precise application control and even coverage across complex surface geometries. Compatible with both plastic substrates and primer surfaces, this adhesion promoter helps prevent coating failures and improves overall finish durability. The product maintains stability for up to 2 years when stored under proper conditions.
Follow standard spray booth safety protocols during application, including adequate ventilation and appropriate respiratory protection. Ensure substrate surfaces are clean and properly prepared before adhesion promoter application for maximum effectiveness.
