Sodium pyrithione (SPT) is the sodium salt of pyrithione (2-mercaptopyridine-1-oxide), a broad-spectrum biocide with strong antimicrobial activity against bacteria and fungi at low concentrations. It is used as an antidandruff active, a preservative in water-based coatings, and an antimicrobial additive for plastics and textiles. SUNCHEM supports international buyers with Sodium pyrithione (SPT) sourcing from qualified Chinese producers, with quality documentation, export coordination, and logistics support.
