Product Features:
The paint film has strong adhesion, hard rust prevention, cathodic protection, solvent resistance, good salt spray resistance, and strong chemical resistance. It is an excellent anti-rust and anti-corrosion primer.

Performance parameters:
1. Color and appearance: gray or light brown, smooth paint film
2. Drying time: surface dry ≤0.5h, hard dry ≤24h
3. Impact strength: ≥50kg•cm
4. Flexibility: 1mm
5. Adhesion (circle method): ≤Level 2
6. Resistance to 10% NaOH, 168h: no foaming, no falling off
7. Salt water resistance (immersed in 3%NaCl, 48h): no foaming, no rust
8. 1000h salt spray test: no rust, no fall off

Construction Instructions:
1. Surface treatment: sand blasting and shot blasting to remove oxide scale, rust and oil, up to Sa2.5 or St3.
2. Substrate temperature: 3°C higher than the dew point.
3. Coating method: brush, roller, spray, high pressure airless spray.
4. Thinner: The epoxy paint thinner is adjusted to the appropriate viscosity for use.
5. Coating thickness: Mix evenly according to the ratio of A and B, and apply after curing for 20 minutes. The dry film thickness is 20-30um.
6. Overcoating interval: about 12 hours at 25℃.
7. Subsequent paints: epoxy intermediate paint, top paint, chlorinated rubber, acrylic, polyurethane, vinyl paint.

Security:
1. The construction site should have good ventilation facilities.
