Antifouling paint is the most common type of paint on the bottom of ocean-going ships. Its main function is to prevent the attachment of marine organisms. Antifouling paint inhibits the growth of attached organisms by slowly releasing biocides (such as copper compounds or other organic active ingredients).

First, use coarse-grain sandpaper (P40-P80) for rough sanding to completely remove rust or old paint film. Then, use medium-grain sandpaper (P120-P180) for secondary sanding to reduce the deep marks left by the coarse sandpaper and provide a good adhesion surface for anti corrosive epoxy primer.

Epoxy floor paint is a high-performance floor coating that is mainly used to provide a strong, wear-resistant and beautiful surface for concrete or other floors. Epoxy primer is a base coating used in a coating system. Its main function is to improve the adhesion of subsequent coatings (such as topcoats).

The types of primers commonly used for rusty metals are: 1. Zinc-rich primer 2. Epoxy primer 3. Zinc phosphate primer 4. Polyurethane primer 5. Red lead primer

Common types of anti-rust paints are 1. Zinc-rich primer 2. Epoxy primer 3. Iron oxide red primer 4. Polyurethane paint In the selection of anti-rust paints, there are many types available on the market, and each paint has its specific anti-rust mechanism and applicable scenarios.

That self etching primer and epoxy primer have their own emphasis on functions and performance, so they cannot simply replace each other. Self etching primer is more suitable for scenes with improved adhesion, while epoxy primer performs well in environments that require durable protection.

Zinc rich primer is a high-performance anti-corrosion coating, mainly composed of a large amount of zinc powder and film-forming substances (such as epoxy resin, alkyd resin, etc.). Zinc rich primer is coated on the metal surface to form a protective film rich in zinc powder, thereby providing long-term anti-corrosion protection.

If both anti-corrosion and wear resistance are required, polyurethane primer and epoxy primer can be used together: first apply epoxy primer as an anti-corrosion layer, and then apply polyurethane primer or topcoat to improve wear resistance and anti-aging performance.

The formula design of the epoxy primer determines its original viscosity. If the product has a high viscosity when it leaves the factory, direct use may cause difficulty in brushing or spraying. At this time, adding an appropriate amount of diluent can reduce the viscosity and improve construction performance.

Epoxy primer is an important part of the anti-corrosion coating system for aluminum products, especially suitable for use in severely corrosive environments. It has excellent adhesion and chemical resistance, and can form a hard protective film on the surface of aluminum to block the intrusion of moisture, oxygen and other corrosive substances.
