# TIN-FREE HYDROLYSIS SELF-POLISHING A/F RAINBOW PAINTS ## Product Code RAINBOACE 200 (SP-200) ## 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, forming a smooth surface to cut fuel consumption drastically without polluting seawater. Its antifouling service life is proportional to dry film thickness. ## Properties 1. Tin-free resin formula, zero 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 ## Specification Data - Color: Reddish Brown, Brown, Blue, Blue-Green - Gloss: Semi-gloss - Volume Solids: 65 ± 2% - Recommended Film Thickness: Wet film 115~230 μm (4.6~9.2 mil), Dry film 75~150 μm (3~6 mil) - Theoretical Coverage Rate: 4.33~8.66 ㎡/L - Compatible Primers: - SP-08: Zinc-free Pre-treatment Primer - EP-05: One-coat Hull Anti-corrosion Primer for Newbuilding & Drydock - EP-111: Universal Full Ship Primer for New Vessels - RA-12: High-build One-coat Rubber Hull Anti-corrosion Primer - RAINBOXY 856 - Specific Gravity: ≥ 1.5 Kg/L - Viscosity: 90 ± 5 KU (25°C) ## Mixing & Thinning - Thinner: No.1407 Rubber Paint Thinner (RP-71) - Thinner Addition Ratio: 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 Condition: Above 26°C (80°F) ## Precautions ⚠️ 1.
