# YUNG FLON PRIMER WHITE (FOR STEEL) RAINBOW PAINTS ## Product Code No.5400MP ## Type Two-component anti-rust primer formulated with special modified epoxy resin and anti-corrosion pigments. ## Application Anti-rust primer for steel pipes, steel frames, bridges and factory steel structures, applied over zinc-rich shop primer to eliminate topcoat bubbling defects. ## Properties 1. Hard, tough film with excellent adhesion 2. Strong adhesion over zinc-rich primer, fills primer pores to prevent topcoat bubbling 3. Excellent abrasion resistance and electrical insulation performance 4. Outstanding resistance to oil, solvents and chemical reagents ## Specification Data - Gloss: Flat - Color: Red Brown - Hiding Power: ≥8 m²/L (mixed paint) - Specific Gravity: ≥1.50 kg/L (mixed paint) - Viscosity: 65~80 KU (25°C) - Drying Time - Tack-free: Within 1 hour (25°C) - Hard dry: Within 6 hours - Full cure: 7 days (25°C) - Film Thickness: Wet film 105 μm, Dry film 45 μm - Theoretical Coverage: 9.5 m²/L, 6.3 m²/kg (@45μm dry film) - Recoating Interval: Minimum 8 hours (25°C) - Mix Ratio: As printed on bucket - Volume Solids: 43% (mixed paint) - Pot Life: 8 hours at 25°C - Thinner: No.1005 Thinner SP-12 - Thinner Dosage: 5~15% by weight (excluding tool cleaning) ## Compatible Primers No.1006 Epoxy Zinc Rich Primer (EP-03AA), No.1011 Inorganic Zinc Primer (IZ-01) ## Compatible Topcoats Full series Rainbow topcoats, polyurethane finish, chlorinated rubber finish, ULI topcoat ## Storage Stability: Minimum 3 years under normal storage ## Application Methods Brush Coating, Airless Spray, Roller Coating ### Airless Spray Parameters - Nozzle size: 0.019" ~0.023" - Air pressure: 5~6 kg/cm², pressure ratio ≥45:1 ## Construction Precautions ⚠️ 1. Mix base and hardener evenly per specified ratio, stand 10~20 minutes for reaction before use. 2. Fully remove moisture, grease, sludge, dust, rust and corrosive salts from substrate surfaces. 3. Avoid construction when temperature below 10°C or relative humidity exceeds 85%RH; fully dry damp surfaces before coating. 4. Clean all coating equipment immediately after use. 5. Maintain full ventilation during confined tank interior construction. ## Note All datasheet data are internal laboratory test results for construction reference only.
