| Message: | Used in non-metal Marine Antifouling paint
It is a metal-free antifouling agent for use in antifouling paints for ship hulls or other marine structures. this product has a broad spectrum of activity against hard-shelled and soft-bodied invertebrate animal fouling organisms. Because of its chemical and physical stability in coatings, the low water solubility and leachability, this product containing antifouling paints can often be specified for multi-year dry-docking intervals comparable to those achieved with copper-based products.
