AI Overview
Copper Pyrithione (CPT) aqueous dispersion is a high-performance, water-based, broad-spectrum antimicrobial agent used primarily in antifouling paints, coatings, and industrial applications to control fungal and bacterial growth. It acts as an insoluble, stable, and low-metal biocide, offering superior long-lasting protection compared to other pyrithiones.
Key details regarding copper pyrithione aqueous dispersions include:
- Composition: Typically contains small, solid particles of copper pyrithione (often 20%–70% by weight) dispersed in water, frequently featuring specific particle sizes for optimal efficacy.
- Performance: Known for being more stable than zinc pyrithiones and less easily removed from dry coating films, enhancing durability in marine environments.
- Applications: Widely used as a biocidal additive in marine paints to prevent algae and bacterial colonization on ships and structures.
- Properties: Functions through the disruption of proton gradients in microbial cells.
Examples include specialized dispersions like Copper Omadine™ AQ 35.
