Calcium is one of the most commonly used auxiliary drier. Although calcium carboxylates exhibit poor drying action by themselves, they, however, boost the performance of secondary (through driers) such lead and zirconium. Calcium driers, especially neutral ones, are used pigment wetting and dispersing agent and enhance hardness and gloss. Calcium significantly reduces the “loss of dry” of the system preventing the pigments adsorbed onto the main drier. Ege Kimya offers both neutral with available 4%, 5% and 6% metal concentrations and overbased (basic) product (10%) which has slightly reduced emulsifying properties than neutral driers. Calcium driers are normally used in conjuction with surface and through driers such as cobalt, manganese, zirconium, lead etc.
