Chlorinated rubber primer
The paint film is dry at room temperature, simple in construction, strong in adhesion, good in corrosion resistance, excellent in water resistance and salt water resistance, excellent in moisture resistance and mildew resistance, and good in acid and alkali resistance. It is an economical anti-corrosion primer.

7. Post-matching paint: chlorinated rubber enamel, acrylic 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.
