Epoxy Zinc Rich Primer (Two-component)
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.
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
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.
1. The construction site should have good ventilation facilities.
2. Construction workers should wear masks, glasses, gloves and other protective equipment to avoid skin contact and inhalation of paint mist and solvents.
3. Smoking is strictly prohibited on the construction site, and all sources of ignition are isolated.
