1. Rigorous Surface Preparation & Blasting
- Abrasive blasting – removes rust, mill scale, and contaminants using steel grit.
- Ensures high cleanliness standard and optimal surface roughness.
- Critical for maximizing adhesion of subsequent anti‑corrosion layers.
2. Zinc‑Rich Primer Application
- Sacrificial anode protection – zinc particles corrode first to protect underlying steel.
- Provides cathodic protection even if top layers are scratched.
- Applied via spray for uniform coverage and precise dry film thickness.
3. Epoxy Intermediate & Topcoat Systems
- Epoxy intermediate coat – delivers exceptional chemical resistance and mechanical strength.
- Durable topcoat – polyurethane or acrylic finish resists UV, moisture, and atmospheric corrosion.
- Ensures decades of structural integrity for the double‑wall fuel tank.
4. Internal Electrostatic & Chemical Resistant Coatings
- Electrostatic dissipation properties – prevents static sparks inside the tank.
- Specialized epoxy or glass flake coatings for water‑prone areas like the tank bottom.
- Resists continuous fuel immersion and chemical degradation, ensuring product purity.
