GP® CK-2103 Resin

Modifier for alkyd and epoxy air dry coatings is designed to improve resistance, hardness, gloss and adhesion. Coatings made with GP® CK-2103 dry faster than those made with GP CK-2432 and darken on drying.

A primary use of GP CK-2103 is in inks. It is good at “wetting out” pigments and has a good balance of softening point and viscosity.
