Frequently Asked Questions
What is zinc pyrithione used for?
Zinc pyrithione (CAS 13463-41-7) is an organozinc biocidal active. Industrial uses include the antimicrobial active in marine antifouling coatings and a preservative against bacterial and fungal growth in metalworking fluids, cosmetic formulations, and textile finishes.
What is the chemical formula for zinc pyrithione?
Zinc pyrithione has the formula C10H8N2O2S2Zn (CAS 13463-41-7), an organozinc complex of two pyrithione ligands coordinated to zinc.
What should zinc pyrithione not be mixed with?
Zinc pyrithione can be destabilized by chelating agents and certain transition-metal ions (notably copper and iron salts), which can cause discoloration or loss of activity. Formulators should run compatibility testing and follow the SDS for handling guidance.
Is zinc pyrithione water soluble?
No. Zinc pyrithione has very low water solubility and is typically supplied and handled as a dispersion or powder. Its low solubility is relevant when formulating coatings, metalworking fluids, and finishes.
How does zinc pyrithione ship under DOT?
Zinc pyrithione is assigned UN 2811 and ships as regulated dangerous goods with appropriate packaging and documentation. RawSource provides the SDS and bulk quotes; confirm shipping requirements for your destination.
