Micaceous iron epoxy intermediate paint (two-component)
The paint film has strong adhesion, hard wear resistance, high rust resistance, salt spray resistance, and good temperature resistance. It is an efficient and long-lasting economical primer.
1. Color and appearance: gray or light brown, smooth paint film
2. Fineness (scraper type): ≤60um
3. Viscosity (coating -4 cups/25℃): ≥50S
4. Drying time: surface dry ≤4h, hard dry ≤24h
5. Impact strength: ≥40kg•cm
6. Adhesion (circle method): ≤Level 2
7. Salt water resistance (immersed in 3%NaCl, 96h): no foaming, no rusting, no falling 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. After curing for 20 minutes, apply 1-2 coats, and the dry film thickness is 60-100um.
6. Overcoating interval: about 12 hours at 25℃.
7. Matching paint: The matching primer is epoxy zinc-rich primer, and the matching topcoat is epoxy asphalt anti-corrosion paint, acrylic enamel, chlorinated rubber enamel, and polyurethane enamel.
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.
