Paint Driers (metal carboxylates) serve as catalysts to promote curing and allow for drying in various alkyd paints and coatings. They are produced by reactions of metallic salts with organic or synthetic acids, dissolved in a hydrocarbon solvent. Paint driers and their metal derivatives are categorized into three groups (Primary, Secondary, and Auxillary) and various combinations of these groups can yield significantly reduced drying times and improved appearance.
Other uses for metal carboxylates include printing inks, lubricants, and fuels.
Produced from highly refined naphthenic acid. These carboxylate types have outstanding light color, excellent stability, minimum odor and low viscosity. Naphthenates are particularly favored when lower water solubility of the carboxylate is necessary.
Produced from synthetic 2-ethylhexanoic acid. Synthetic acids are used in place of naturally occurring acids as they offer low odor, enable higher metal contents and consistent quality. Compared to Naphthenates, these carboxylates types offer better color, lower odor and fairly greater efficiency.
