Manganese Octate Drier
Whatsapp Order
Manganese Octate Drier is a metal-organic compound commonly used as an oxidative catalyst in alkyd and oil-based coating systems. It is a manganese salt of 2-ethylhexanoic acid (octanoic acid) dissolved in a compatible organic solvent, typically white spirit or hydrocarbon thinner. At a 10% metal concentration, this drier functions as a primary oxidative (surface) drier, accelerating the polymerization and hardening of unsaturated oils and alkyd resins upon exposure to air. It exhibits a dark brown to violet color, has low viscosity, and is highly effective in small doses.
