Oxidative Drier Blend
A ready-to-use oxidative drier blend combining cobalt, zirconium, and calcium metal soaps in optimized ratios for maximum drying performance in alkyd ink and varnish systems. Zirconium provides robust through-drying and hardness development, calcium prevents surface wrinkling, and cobalt delivers fast surface oxidation. The blend simplifies formulation by replacing multiple individual driers with a single, pre-balanced additive.
