BYK® -4512

Technical Datasheet | Supplied by BYK
BYK® -4512 by BYK is a solution of a polymer with functional groups. Acts as an adhesion promoter for solvent-borne systems. Improves adhesion after water immersion and forming processes, for example, deep-drawing, T-bend, and corrosion resistance in coil coatings. It is particularly well-suited for use in chromate-free primers and on metal substrates that are pre-treated in a chromate-free manner. It reacts with melamine resins and polyisocyanates and is cross-linked into the polymer matrix. Improves the adhesion of coatings, which are applied directly onto metal or glass in industrial coatings. The additive is particularly well-suited for use in 2K systems and baking coatings. BYK® -4512 is used in coil and industrial coatings. Recommended dosage is 1-4% of additive based upon total formulation. It has a shelf life of 36 months at 20°C.
