The impact of harmful substances in marine antifouling paint on the marine ecosystem is one of the main reasons for prohibiting its use. The marine ecosystem is complex and sensitive, and harmful substances in marine antifouling paint may destroy the balance of this system.

For some special ships, such as merchant ships or fishing boats, which have long sailing time and are usually in a harsh environment, these ships may require thicker antifouling paint coatings, and the coating thickness is generally between 250 and 300 microns.

Chemicals contained in self polishing antifouling paint: 1. Polymer matrix 2. Antifouling active substances 3. Fillers and additives 4. Solvents The polymer matrix is ​​the main component of self-polishing antifouling paint and directly determines the dissolution behavior and durability of the coating.

Antifouling paint is a type of paint used on the surface of ships to prevent marine organisms (such as algae, shellfish, snails, etc.) from adhering to the surface of the hull. These coatings can significantly improve the navigation performance of the hull, reduce fuel consumption, extend the life of the ship, and reduce the negative impact of ships on the environment.

Traditional paints are usually unable to effectively deal with the attachment of marine organisms, while modern antifouling paints use special formulas and technologies to prevent the attachment of organisms while maintaining the smoothness of the bottom of the ship, reducing water resistance and improving navigation efficiency.

If the ship is docked in a port, swamp or near a marine biological breeding area for a long time, the hull may be at risk of a large number of marine organisms attaching. In this case, antifouling paint can effectively prevent the attachment of marine organisms, reduce the underwater friction of the hull, and avoid the formation of biofilms.

Self-polishing antifouling paint is a special coating that gradually polishes and releases antifouling active substances through chemical reactions with seawater, thereby preventing the attachment of marine organisms. Unlike hard antifouling paint, self-polishing antifouling paint will gradually consume during use, keeping the surface of the hull smooth and clean.

The main function of antifouling paint is to prevent marine organisms from attaching to the underwater part of the hull, thereby reducing hull resistance, reducing fuel consumption, and extending the life of the hull.The main function of primer is to enhance the adhesion between the substrate

● Leisure yachts: Usually used in freshwater or coastal waters, antifouling paint can effectively keep the bottom of the ship clean and improve navigation efficiency. ● Commercial ships and fishing boats: Long-term sailing at sea, antifouling paint is a necessity, which can significantly reduce maintenance costs and fuel consumption. ● Sailing and rowing boats: The speed requirement is high. Antifouling paint can reduce the resistance of the bottom of the ship and increase the speed.

The main types of ship antifouling paints are: 1. Conventional Antifouling Paints 2. Self-Polishing Copolymer Paints (SPC) 3. High-Performance Antifouling Paints 4. Non Toxic Antifouling Paints 5. Hydrophilic Antifouling Paints.
