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.

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.

For ships that are docked in freshwater for a long time, antifouling paint needs to be applied to reduce biological attachment. Aluminum and steel hulls are susceptible to corrosion from electrolytes in freshwater. Applying marine bottom paint can provide an additional layer of protection etc..

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...
