Properties of perchloroethylene paint
Thread Content
Is perchloroethylene paint suitable as an anti-corrosion coating for steel components such as outdoor railings and ladders in coastal areas? Please help me analyze this. The basis for my choice is page 357 of the national standard 05J909; coastal areas are affected by marine atmosphere, but the impact of industrial atmosphere is not significant. However, it has been found that this type of paint does not have very good adhesion, but it does offer good corrosion resistance. The standard GB50046-2008 does not provide any relevant recommendations regarding its use.
Detailed product description of perchloroethylene anti-corrosion paint: It is composed of perchloroethylene resin, acrylic resin, alkyd resin, plasticizers, pigments, additives, solvents, etc. The main features are fast drying of the paint film, a smooth and shiny finish, as well as good weather resistance and chemical resistance. Its main applications are in the painting of various vehicles, machine tools, electrical equipment, agricultural machinery, anti-corrosion equipment, etc. Packaging specification: 20 kilograms per barrel. Technical specifications:

Hardness (using a double-pendulum tester): ≥0.4. Impact resistance, Kg·cm: 50. Flexibility, mm: ≤2. Adhesion (using the scratch test), grade: ≤2. Content of non-volatile substances, %: Red, blue, black ≥26; other colors ≥31. Coverage (based on the dry film), g/m²: Black ≤20; dark shades ≤40; light shades ≤50; white, bright blue ≤60; red ≤80; yellow ≤90; dark blue, purplish-red ≤100; lemon yellow ≤120. Water resistance (in distilled water at 25°C for 24 hours): No bubbling or peeling; slight whitening is allowed.
Complementary paints: Primer – G06–4 Iron Red Vinyl Chloride Primer; Topcoat – G01–1 Vinyl Chloride Clear Coat.
Surface preparation: The surface of metal parts must be degreased, rust-removed, and free of debris.
Application methods: Air spraying. Diluent: Vinyl chloride paint diluent. Dilution ratio: 30–100%. Air pressure: 4.0–5.5 kg/cm². Number of coats: 2–3. Time required for leveling: 10–15 minutes. Optimal temperature and humidity for application: 15–35°C, 45–80%. Recommended dry film thickness: 30–40 μm.
Moisture inhibitor: When humidity is above 70%, a vinyl chloride paint moisture inhibitor should be used.
Storage and transportation: Store in a cool, dry, and well-ventilated place. Shelf life: 12 months.
Precautions: This product is a flammable and explosive liquid with certain toxic properties. Proper ventilation must be ensured at the construction site, and safety measures such as fire prevention, anti-static measures, and protection against poisoning should be taken. It is necessary to follow the safety procedures and regulations for painting operations.
