Barium Naphthenate Paint Dryer from Japan
Barium naphthenate acts as a polymerization catalyst and dryer in oil-based paints and inks, derived from water-insoluble naphthenic acid salts. It is covered by HTS 3824.99.7550 as other esters and salts of naphthenic acids for industrial use. This accelerates drying in alkyd formulations without affecting color.
