Sichuan Chengdu/Yunnan Paint and Coating Sales; Keshisi Metal Anti-Rust Paint (Manager Sun: 152^0825^6966) Metal anti-rust paint is a protective coating specifically designed for metal surfaces. It forms a dense layer to isolate moisture, oxygen, and corrosive media, delaying metal corrosion and extending service life. It is widely used in industrial equipment, building steel structures, ships, automobiles, and other fields.

Main Types and Characteristics
Classified by Film-Forming Substance
Epoxy Anti-Rust Paint: Strong adhesion, resistant to chemical corrosion, suitable for humid environments (e.g., underground pipelines, chemical equipment).
Alkyd Anti-Rust Paint: Low cost, easy application, suitable for outdoor steel structures (e.g., bridges, wrought iron railings).
Polyurethane Anti-Rust Paint: Excellent weather resistance, UV resistant, commonly used in automobiles, ships, and other fields.
Water-Based Anti-Rust Paint: Environmentally friendly, low VOC content, suitable for indoor or environmentally sensitive scenarios.

Performance Advantages
Rust Prevention and Durability: Effectively resists corrosive environments such as salt spray, humidity, heat, acids, and alkalis.
Strong Adhesion: Bonds tightly with metal substrates like iron, aluminum, and galvanized layers.
Easy Application: Can be brushed, sprayed, or rolled; some products support application over rust.
Broad Compatibility: Can be used as a primer in combination with topcoats (e.g., acrylic topcoat, fluorocarbon topcoat).

Application Steps and Precautions
Surface Preparation:
Remove rust (sandblasting or manual grinding to Sa2.5 grade), treat oil stains, and old coatings.

Paint Mixing:
Mix curing agent in proportion (for two-component products), let stand for maturation for 10-15 minutes.

Coating Application:
Apply 2-3 coats, with 4-8 hours between each coat (adjust based on environmental humidity).

Drying Conditions:
Temperature 5-35°C, relative humidity ≤80%, avoid application during rain or snow.

Precautions:
Ensure ventilation during application; wear protective gear (e.g., mask, gloves).
Keep away from open flames before curing; water-based products require frost-proof storage.
