BYK-Chemie Introduces New Adhesion Promoters

Published on 2007-01-22. Author : SpecialChem

BYK®-4500 improves adhesion of aqueous systems on old alkyd coatings.

Adhesion Promoter for Aqueous Emulsion Paints and Alkyd Emulsions Applied on Aged Coatings

The additive improves adhesion (especially wet-adhesion) of aqueous systems on old alkyd coatings. This also applies to substrates that cannot be sanded prviously because accessibility is difficult. BYK®-4500 is easy to incorporate and does not influence storage stability and drying behavior. Dry film properties such as gloss, hardness, flexibility, or tendency to yellowing are not influenced either.

BYK®-4510 improves adhesion on steel, galvanized steel, aluminum, copper and other metals.

Adhesion Promoter for Metal Substrates

The additive improves adhesion on steel, galvanized steel, aluminum, copper and other metals. It is recommended for baking systems based on acrylic/melamine, alkyd/melamine, polyester/melamine, and also for coil coatings on galvanized steel. After neutralization (with, e.g., DMEA) it can also be used in water-soluble systems. BYK®-4510 has no negative influence on storage stability and weather resistance of the coating. Drying behavior as well as hardness and flexibility are not or only insignificantly influenced
