JSYA-CUO Copper Oxide Antimicrobial is inorganic cupric oxide powder with CAS 1317-38-0. It acts as powerful biocide widely used in marine antifouling coating systems. Copper ions released slowly can restrain the adhesion and growth of barnacles, algae, shellfish and mold on submerged surfaces. It is compatible with solvent-based and waterborne marine coating formulas, delivering long-term antifouling and anti-mold performance for marine facilities.
JSYA-CUO is fine black cupric oxide powder. The material releases copper ions gradually when exposed to water environment to prevent marine organism attachment and mold proliferation. It features good weather resistance, water resistance and chemical stability, and keeps stable in coating curing process.
Main advantages:
Typical applications:
JSYA-CUO cupric oxide is a classic and reliable biocide for marine coating industry, reducing biofouling and mold growth on marine substrates exposed to seawater and humid atmosphere.
