Lead Octoate
Lead Octoate is a viscous liquid solution containing 30% lead octoate, a metal soap derived from lead and 2-ethylhexanoic acid (also known as octanoic acid). It is primarily used as a drying agent (drier) in paints, varnishes, and coatings to accelerate the curing process by promoting oxidation and polymerization of drying oils. This product is widely employed in industrial coatings to improve drying times, hardness, and durability of surface films. Packaged typically in 250kg drums, Lead Octoate 30% is handled with care due to the toxic nature of lead compounds.
