What is Copper Umiguard Paste Marine Biocide?
Copper Umiguard Paste is a viscous dispersion system composed of Copper Umiguard Powder, rosin and xylene, with Copper Pyrithione (CPT) as its active ingredient. As a marine antifouling agent, this product is widely used in antifouling coating systems for ships and underwater facilities.
Applications
- Marine antifouling coatings
- Antifouling coatings for marine underwater facilities
Advantages
- Significantly inhibits the growth of both Gram-negative and Gram-positive bacteria
- Inhibits the growth of fungi (yeasts, molds) and algae
- Nearly insoluble in water, providing sustained-release, long-lasting antifouling
