Product Overview:
QM-7023 is a hyperbranched polyester adhesion promoter, suitable for both water and oil applications, with excellent resin compatibility. Containing active groups that react with metal substrates, QM-7023 can be used in solvent-based, water-soluble, or water-based amino baking paints. It significantly increases the adhesion of coatings to various metal substrates such as magnesium-aluminum alloys, iron, aluminum, nickel, and stainless steel, and improves the water resistance, salt spray resistance, flexibility, and impact resistance of the paint film.
