OCTA-SOLIGEN CALCIUM 7 HS NEUT

Calcium itself has no drying effect on binders that dry by oxidation. However, it yields synergistic effects in combination with primary driers such as cobalt and manganese and with secondary driers such as zirconium.When added during grinding, it prevents adsorption of the primary driers at the surface of the pigments, thus stabilizing the drying power. Calcium also promotes pigment wetting and the neutral supply forms improve film gloss.
