Anti Fouling Agent：Copper Pyrithione Powder

In the marine environment, ships, offshore platforms, and other underwater structures are often subjected to severe corrosion. The saltwater, microorganisms, algae, and other factors can not only reduce the lifespan of equipment but also affect its safety and operational efficiency. Traditional anticorrosion methods, such as coatings and cathodic protection systems, are effective but still face challenges such as frequent maintenance, high costs, and potential environmental pollution. In recent years, Copper Pyrithione (CuP), as a novel anticorrosive agent, has gained widespread use in marine anticorrosion due to its excellent antimicrobial, antifungal, anti-algal, and anticorrosive properties.

Copper Pyrithione is a compound formed by the combination of Copper ions and Pyrithione molecules. Its structure contains elements that have antimicrobial, anti-algal, and antifungal effects. The copper ion is the primary active component, which acts through electrochemical reactions to provide anticorrosion benefits, while Pyrithione enhances its antimicrobial effects through its sulfur-containing groups, which form complexes with metal surfaces. Copper Pyrithione is stable in water and can continuously release copper ions, exerting long-lasting inhibitory effects on algae, bacteria, and fungi.

Our Kabasph brand Copper Pyrithione powder features for a broad-spectrum, low-toxic antibacterial and antifungal agent for fungi and bacteria, which is widely used for anti-fouling antimicrobial for marine antifouling coatings, coatings, adhesives and so on.
