Product features and advantages

VOK®- AP 4513 is used as adhesion promoter of metal substrate in waterborne epoxy coating system. Increase the adhesion and mechanical elasticity of wet film and dry film, and improve the corrosion resistance of the coating. The polymer characteristics of VOK®-4513 and its good adhesion on the metal-coat interface make the paint film more flexible. VOK®- 4513 does not contain silane and has better storage stability.
