Product name: Epoxy Primer
Product introduction
Epoxy primer coat is a two-component, high build primer coat based on high molecular weight epoxy resin. It has good heat and humidity resistance, salt spray resistance, excellent water resistance, oil resistance, alkali resistance, weak acid resistance and salt water resistance properties. Coat film is tough, smooth, mildew-proof, and pollution-resistant, with excellent impact resistance, abrasion resistance, and excellent adhesion properties.
Application
Used as a primer for anti-corrosion paint systems on steel structures and other substrates. It is mainly used for interior decoration of steel and concrete that have been coated with epoxy primer and anti-corrosion topcoat. It can also be used for structural coating of indoor equipment such as ship cabins, inner walls of pipes, and walls of workshops that are not exposed to sunlight.

Construction technology
1. Basic treatment
Clean up the rust, weld coating, welding spatter, oil stain, dust and other debris on the coating part, so that the coated surface is free of rust, oil, water, and dust. Primer must be applied within 12 hours after rust removal.
2. Primer coating
When the primer is applied, the direction should be consistent and the connection should be neat. When painting, the principle of frequent movement and short distance is adopted to prevent too much paint from flowing down.
3. Topcoat coating
Prepare according to the ratio of A:B=10:1 and stir thoroughly to ensure consistent color, viscosity and consistency without sagging and brush lines. It should be stirred continuously during use, and the application method is the same as that of the primer.
Recommended cost-effective solution for normal and low-pollution environment to increase service life:
Epoxy primer coat + Polyurethane topcoat
