Anti-fouling paint is a specialized category of coatings applied as the outer (outboard) layer to the hull of a ship or boat, to slow the growth of and facilitate detachment of subaquatic organisms that attach to the hull and can affect a vessel's performance and durability.
Pettit Marine Paint is a manufacturer of marine (boat) coatings, antifouling boat bottom paint, varnish and epoxies for consumer and commercial markets. The company was established in 1861, its headquarters are located in Rockaway , New Jersey .
For 40 years TBT was used as a biocide in anti-fouling paint, commonly known as bottom paint, applied to the hulls of oceangoing vessels. [2] Bottom paint improves ship performance and durability as it reduces the rate of biofouling, the growth of organisms on the ship's hull. The TBT slowly leaches out into the marine environment where it is ...
Antifouling paint (or bottom paint) is used to protect the hulls of boats from fouling by marine organisms. Antifouling paint protects the surface from corrosion and prevents drag on the ship from any build-up of marine organisms. These paints have contained organotin compounds such as tributyltin, which are considered to be toxic chemicals ...
Most antifouling coatings are based upon chemical compounds that inhibit fouling. When incorporated into marine coatings, these biocides leach into the immediate surroundings and minimize fouling. The classic synthetic antifouling agent is tributyltin (TBT). Natural biocides typically show lower environmental impact but variable effectiveness.
Anti-fouling is the ability of specifically designed materials (such as toxic biocide paints, or non-toxic paints) [1] to remove or prevent biofouling. [2] The buildup of biofouling on marine vessels poses a significant problem. In some instances, the hull structure and propulsion systems can be damaged. [3]
