# TIN-FREE HYDROLYSIS SELF-POLISHING A/F RAINBOW PAINTS ## Product Code RAINBOSEAL 800 ## Type Long-service self-polishing antifouling bottom coating formulated with tin-free functional metal silyl copolymer and inorganic biocide. ## Application Long-term antifouling coating for ship hull bottoms. The coating film wears evenly under water flow impact, delivering a smooth seal-like surface that greatly reduces fuel consumption without polluting seawater. Its antifouling service life is proportional to dry film thickness. ## Properties 1. Tin-free resin formula, no pollution to marine environment 2. Gradually polished by water flow to maintain fresh and smooth film surface 3. Smooth coating reduces fluid resistance to save fuel 4. Tough coating film 5. Ultra-fast drying speed 6. Suitable for medium & low-speed vessels ## Specification Data - Color: Reddish Brown, Brown, Blue, Blue-Green, Black - Gloss: Semi-gloss - Volume Solids: 56 ± 2% - Recommended Film Thickness: Wet film 134~268 μm (5.36~10.72 mil), Dry film 75~150 μm (3~6 mil) - Theoretical Coverage Rate: 3.73~7.46 ㎡/L (0.13~0.27 L/㎡) - Compatible Primers: - SP-47: Universal Full Ship Primer for New Vessels (EP-111) - SP-50: One-coat Hull Anti-corrosion Primer for Newbuilding & Drydock (EP-05) - SP-47-1: Universal New Construction Primer (EP-116) - SP-71: Fresh Water Tank Coating - Specific Gravity: ≥ 1.5 Kg/L - Viscosity: 90 ± 10 KU (25°C) ## Mixing & Thinning - Thinner: No.1407 Rubber Paint Thinner (RP-71) - Thinner Addition Ratio: 0~10% 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: At least half a year under normal storage conditions - Storage Temperature: Above 26°C (80°F) ## Precautions ⚠️ 1.
