Calcium Drier

Calcium Drier is a metal-based drying agent primarily composed of calcium salts of fatty acids (commonly calcium octoate or calcium linoleate), widely used as a siccative in paints, varnishes, inks, and coatings. It functions as a catalyst to accelerate the oxidative cross-linking and polymerization of drying oils, leading to faster drying times and improved film hardness and durability. Calcium Driers are valued for their good compatibility with other driers, low toxicity, and efficient catalytic activity at low concentrations. They are commonly used alone or in combination with other metal driers such as cobalt or manganese driers for optimized drying performance.
