Copper Pyrithione Chemical Properties,Uses,Production

Chemical Properties

Copper pyrithione is a green crystalline fine powder with high stability, stored under light-proof conditions, the content remains unchanged for two years, mainly used in the production of daily chemical products, adhesives, paints, coatings, paper, pharmaceuticals, leather and other industries.
Copper pyrithione

Uses

Copper pyrithione is intended to be used as a co-biocide (booster biocide) by both professional and non-professional users in antifouling products (PT 21) against marine fouling species. It is meant to be effective against soft-fouling organisms, so its function is to increase the efficacy of the product in order to remove the most problematic fouling organisms.

Application

Copper pyrithione, [Cu(PyS)2] is used as an additive to protect paints (such as industrial and marine) against microbe (algal, fungal and bacterial) and crustacean growth. It acts as a low metal fouling agent with long-lasting efficacy that does not induce galvanic corrosion making it suitable for metal hulls and marine environments.

Definition

Copper pyrithione belong to a class of cyclic sulfur organo products containing sulfur atom (S) and often oxygen (O), nitrogen (N), hydrogen (H), as well as other elements, can find application for making biologically active agents such as antiviral, antibacterial, antifungal agents. It is an effective inhibitor of microbe growth including algal, fungal (molds & yeasts) and bacterial (gram-positive & gram-negative).

Antimicrobial activity

Copper Pyrithione Cu Powder possesses a broad spectrum of antifungal and Antialgal activity against all fungi and algae including following relevant organisms. This product can restrain and sterilize eight moulds, five bacteria, as well as two yeast fungis which are distillery yeast and bakers'yeast. It's MIC to various micro-organisms as follows:
Microorganisms MIC(PPM)
Aspergillus niger 20 Cladosporium herbarium 6 Escherichia coli 8 Aspergillus flavus 20 Trichoderma viride 8 Pseudomonas fluorescens 18 Aspergillus versicolor 18 Chaetomium globosum 6 Staphylococcus aureus 6 Penicillium citrinim 8 Bacillus subtilis 8 Saccharomyces cerevisiae 6 Pacillomyces varioti 8 acillus megaterium 6 Klocckeria Janke 8

Hazard

Moderately toxic by ingestion, inhalation, and skin contact.
