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.

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 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.

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.

Check Digit Verification of cas no

The CAS Registry Mumber 14915-37-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,9,1 and 5 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 14915-37:
(7*1)+(6*4)+(5*9)+(4*1)+(3*5)+(2*3)+(1*7)=108
108 % 10 = 8
So 14915-37-8 is a valid CAS Registry Number.
