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.
