BYK-4512

Adhesion promoter for solvent-borne systems applied to metal substrates. In coil coatings, BYK-4512 improves adhesion after water immersion and forming processes, for example deep-drawing, T-bend, and corrosion resistance. It is particularly well-suited for use in chromate-free primers and on metal substrates that are pre-treated in a chromate-free manner. BYK-4512 reacts with melamine resins and polyisocyanates and is cross-linked into the polymer matrix. In industrial coatings, BYK-4512 improves the adhesion of coatings, which are applied directly onto metal or glass. The additive is particularly well-suited for use in 2K systems and baking coatings. Recommended for coil and industrial coatings.
