Calcium Octoate 10%
Whatsapp Order
Calcium Octoate 10% is an aqueous solution containing 10% calcium octoate, a calcium salt of 2-ethylhexanoic acid (octanoic acid). It is a white to pale yellow liquid, soluble in water, known primarily as a metal carboxylate used as a drying agent and corrosion inhibitor. It functions as a calcium-based drier in coatings, paints, varnishes, and printing inks to accelerate the curing process by catalyzing the oxidation and polymerization of drying oils. Due to its stability and efficacy at low concentrations, it is widely preferred as a non-toxic alternative to traditional lead or cobalt-based driers.
