1. Choose high-performance protective coatings
Use a combination of epoxy low-surface-area primer and self-cleaning polyurethane topcoat. No rust removal is required before spraying. It is resistant to salt spray and abrasion, reducing overall maintenance costs by 40%.
High-zinc content cold-galvanized paint (such as Robaroo coatings) provides cathodic protection, with salt spray resistance exceeding 1000 hours, suitable for high-salt and high-humidity environments.
2. Regular maintenance and inspection
Inspect the coating condition quarterly, paying particular attention to easily corroded areas such as welds and joints, and repair any damage promptly.
Use rust-preventive oil (such as petroleum jelly) to lubricate metal parts and form a protective film.
3. Optimize environmental adaptability
Add UV absorbers (such as benzotriazoles) or light stabilizers (HALS) to slow down photodegradation.
Avoid prolonged exposure to extreme climates; use sunshades to reduce direct UV radiation when necessary.
4. Application and Storage Specifications
During application, ensure uniform coating thickness (e.g., epoxy primer + polyurethane topcoat to 200μm).
Store in a dry, well-ventilated place with humidity ≤70%, away from corrosive substances.
