Adhesion promotors - applications

Adhesion principle

An adhesion promotor is a substance which is applied to a substrate to improve the adhesion of a coating or adhesive. Sartomer products contain carboxylic or phosphoric acid groups interacting effectively with the functionalities present on the surface of the substrates though covalent, ionic, or hydrogen bonds.
