Boat Antifouling Paint (Copper, Tributyltin Legacy) — outdoor safety profile
Moderate riskBoat hull antifouling paints preventing marine organism attachment.
What is this product?
Boat hull antifouling paints preventing marine organism attachment. Tributyltin (TBT) was banned globally (IMO 2008) after devastating marine ecosystem impacts — including imposex (sex change) in gastropods at <1 ng/L concentrations. Current antifouling paints use copper oxide (Cu2O) at 30-75% — now documented to cause similar ecosystem damage in marinas and harbors. Washington State has restricted copper antifouling. Non-biocidal alternatives exist but require more frequent cleaning.
