Anti fouling is the process of removing or preventing the accumulation of marine organisms from the surface of hull and the paint used for this application is called anti fouling paint.

Antifouling paint is a type of paint that is specifically designed to prevent the growth of organisms, such as algae, barnacles, and other marine organisms, on the surface of boats, ships, and other underwater structures. These organisms can attach themselves to the surface, causing damage, reducing efficiency, and increasing fuel consumption.

Commercial transport ships, especially large ships such as tankers, container ships, and bulk carriers, are often exposed to seawater during long-term voyages. Since these ships need to sail for a long time in a large area of ​​sea, the bottom of the ship is exposed to seawater for a very long time, so antifouling bottom paint is essential for them.

It has the functions of anti-corrosion, anti-fouling and enhancing the smoothness of the hull surface. According to the purpose and construction process, boat bottom paint is usually divided into three layers: primer, intermediate paint and topcoat, and each layer of paint has its unique role.

The initial drying time of epoxy paint is 6-8 hours, and the full curing time is 24 hours; the initial drying time of polyurethane paint is 8-12 hours, and the full curing time is 48 hours; the initial drying time of antifouling paint is 4-6 hours, and the full curing time is 24-48 hours.

The best marine bottom paint should have 6 major properties: 1. Anti-corrosion, 2. Anti-fouling, 3. Adhesion, 4. Abrasion resistance, 5. Environmental protection, 6. Convenient construction ● Easy to paint ● Quick drying ● Strong covering power.

Generally speaking, the service life of marine bottom paint is about 1 to 5 years, among which the service life of hard antifouling paint is generally about 2 to 3 years. Self-polishing antifouling paint has a longer service life, generally between 3 and 5 years...

​Boat bottom paint, also known as antifouling paint, is a coating specially applied to the bottom of a boat. Its main purpose is to protect the bottom of the boat from the attachment and erosion of marine organisms, while improving the navigation performance and fuel efficiency of the boat.
