Additives for UV LED EB applications
Sartomer's unique range of specialty additives provides adhesion, surface effects, and enhanced performance to the following applications:
Adhesion
Adhesion principle:
An adhesion promoter 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 through covalent, ionic, or hydrogen bonds.
Adhesion promoters range:
