Asphalt anti-corrosion paint
The paint film is smooth and soft, with excellent water resistance, moisture resistance, acid and alkali resistance, good anti-corrosion performance, strong rust resistance, and easy to brush. It is an economical and low-cost high-quality anti-corrosion material.
1. Color and appearance: black, smooth paint film
2. Viscosity (coating -4 cups/25℃): 60-80S
3. Drying time: surface dry ≤2h, hard dry ≤24h
4. Non-volatile content: ≥45%
5. Adhesion: ≤Level 5
6. Salt water resistance (immersed in 3% NaCl, 48h): no foaming, no falling off
7. Alkali resistance (immersion in 10% NaOH, 48h): no foaming, no falling off
8. Acid resistance (immersion in 10% H2SO4, 48h): no foaming, 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. Diluent: The special diluent is adjusted to the appropriate viscosity for use.
5. Coating thickness: 2 coats, dry film thickness 50-100um.
6. Overcoating interval: about 12 hours at 25℃.
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.
