Red antifouling paint is not only due to the color of copper oxide, but also because it has a visual warning effect. The bottom of a ship is difficult to see in the water, and red can be more conspicuous in shallow waters and dry docks, making it easier to inspect and maintain.

The importance of antifouling ship bottom paint: improve navigation efficiency (the presence of bottom attachments can cause the fuel efficiency of ships to drop by up to 30%), protect the hull structure, and reduce maintenance costs.

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...

​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.
