Kopthione Cu Powder is a light green crystalline type fine powder. It exhibits pronounced growth inhibiting activity against a broad spectrum of both gram negative and gram positive bacteria. Inhibits the growth of fungi, both yeast and mould. It is insoluble in water and inhibits the growth of algae. It is used as a marine antifouling agent. It is used as a marine antifouling agent. It is used in marine paints when a more gelling resistant antifoulant is required.

Features
Copper Pyrithione is intended to be used as a co-biocide (booster biocide) by both professional and non-professional users in antifouling products 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.
Functional Activity: Algaecide, bactericide and Fungicide.
Guideline application: Antifouling paint in marine and yacht applications, controls algae in fishnet by coating.
Benefits:
Broad spectrum antimicrobial
Excellent heat and pH stability
No VOC's
Low water solubility = low leach rate = long term protection
Extensively tested toxicology and environmental profits
Normal addition levels are in the range 2 to 4% by weight
