| Advantages
|
| Metal-free antifouling agent
|
| • Low use concentrations provide cost-effective alternative to copper-based antifoulants
|
| • Broad spectrum control of hard fouling organisms
|
| • Long-lasting efficacy
|
| • Effective in marine and freshwater environments
|
| • Breaks down rapidly in the aquatic environment
|
| • Does not induce galvanic corrosion, particularly suitable for metal hulls including aluminium
|
| • Provides paint formulation flexibility including bright colours and improved colour retention, lower VOC as well as water based paints |
