Product Desciption
Zinc Pyrithione (ZPT)
CAS No.: 13463-41-7
Molecular Formula: C10H8N2O2S2Zn
Formula Weight: 317.4
Structural Formula:
Properties:
The pyrithione ligands, which are formally monoanions, are chelated to Zn2+ via oxygen and sulfur centers. In the crystalline state, ZPT exists as a centrosymmetric dime, where each zinc is bonded to two sulfur and three oxygen centers. In solution, however, the dimers dissociate via scission of one Zn-O bond. Pyrithione is the conjugate base derived from 2-mercaptopyridine-N-oxide (CAS No. 1121-31-9), a derivative of pyridine-N-oxide.
Specifications:
Uses:
Due to its low solubility in water (8ppm at pH 7), ZPT is suitable for use in outdoor paints and other products that provide protection against mildew and algae. It is an effective algaecide. ZPT is chemically incompatible with paints relying on metal carboxylate curing agents. When used in latex paints with water containing high amount of iron, a sequestering agent that will preferentially bind the iron ions is needed. Its decomposition by ultraviolet light is slow, providing years of protection even against direct sunlight.
Package and Storage:
Stored in tightly closed containers in a cool, dry area. Avoid light. Content is unchanged in two years.
