Calcium Naphthcuate CAS NO.61789-36-4

 Calcium:
Calcium is known as an auxiliary drier, usually used in combination with cobalt. It can modify the balance of top dry and through dry, reducing wrinkling. It avoids the loss of drying because the complex compound of calcium and cobalt prevent the cobalt from being absorbed by the pigment. It is possible to replace parts of the lead with a large amount of calcium to prevent the precipitation of the lead and maintain drying efficiency. Calcium is also useful as pigment wetting and dispersing agents and help to improve hardness and gloss and reduce skinning and crater.
