Applications. Zinc Pyrithione is an antimicrobial and is used around the world in a variety of applications, including antifouling paints, building products, plastics, polyurethane products, textiles and antidandruff shampoos. It is also used as a preservative in personal care products, used in building products, plastics and polyurethane products, as well as biocide in textiles.

ZPT is a superordinary anti-scale agent and anti-lipid overflow agent. It can effectively eliminate eumycete which produces dandruff, and result in relieving itching, removing dandruff,
diminishing phalacrosis and deferring poliosis. Therefore, it is considered as a highly effective and safe product. It will add the value of
shampoo and meet the high demands from consumers. For this reason, ZPT is widely used in the production of shampoo. Moreover, as a fine, broad-spectrum, environment -friendly and low toxic antiseptics, it can be used in civil coating, adhesive and carpet. The mixture of
ZPT and Cu2O also can be used as marine antifouling coating to prevent adhering of shells, seaweeds and aquatic organisms to hulls.
ZPT and its relative products enjoy tremendous potential and broad space in pesticide field with properties of highly efficiency,environmental protection, hypotoxicity and broad-spectrum.
