# TIN-FREE HYDROLYSIS SELF-POLISHING A/F RAINBOW PAINTS ## Product Code RAINBOACE 120 (SP-120) ## Type Long-acting self-polishing antifouling coating composed of tin-free functional metal silyl copolymer and inorganic biocide. ## Application Long-term bottom antifouling coating for ship hulls. The coating film polishes uniformly under water flow impact, delivering a smooth surface that significantly reduces fuel consumption and avoids seawater pollution. Its antifouling service life is proportional to the dry film thickness. ## Properties 1. Tin-free resin formula, no marine environmental pollution 2. Gradually polished by water flow to maintain a fresh, smooth coating surface 3. Smooth film minimizes fluid resistance, saving approximately 4% fuel consumption 4. Tough coating film 5. Ultra-fast drying speed ## Specification Data - Color: Reddish Brown, Brown, Blue, Blue-Green, Black - Gloss: Semi-gloss - Volume Solids: 64 ± 2% - Recommended Film Thickness: Wet film 157~235 μm (6.2~9.4 mil), Dry film 100~150 μm (4~6 mil) - Theoretical Coverage: 4.25~6.36 ㎡/L - Compatible Primers: - SP-47: Universal Full Ship Primer (EP-111) - SP-50: One-Coat Hull Anti-Corrosive Primer (EP-05) - SP-47-1: Universal New Construction Primer (EP-116) - SP-71: Fresh Water Tank Coating - Specific Gravity: Min. 1.5 Kg/L - Viscosity: 100 ± 10 KU (25°C) ## Mixing & Thinning - Thinner: No.1407 Rubber Thinner (RP-71) - Thinner Dosage: 0~3% by weight ## Application Method Airless Spray ### Airless Spray Operating Parameters - Nozzle Size: 0.021" ~ 0.035" - Secondary Air Pressure: 5 ~ 6 Kg/cm² - Pressure Ratio: 45 : 1 or higher ## Drying Time - Tack-free: Within 1 hour - Hard Dry: Within 6 hours (25°C) ## Recoating Interval Minimum 6 hours (25°C) ## Storage Stability - Shelf Life: 1 year under normal room temperature storage - Storage Temperature: Above 26°C (80°F) ## Precautions ⚠️ 1.
