# HEAT-RESISTING TOP COATING RAINBOW PAINTS ## Product Code No.1569 ## Type Two-component topcoat made of moisture-cured inorganic polymer, matched with heat-resistant and weather-resistant pigments; fully cures at ambient temperature without heating. ## Application Topcoat for high-temperature anti-corrosion coating systems to boost overall weather resistance. ## Properties 1. Excellent heat resistance, withstands up to 650°C continuous temperature 2. Hard dry within 8 hours at ambient temperature 3. Can be sprayed over No.1566, 1567, 1568, IZ-01 and other matching heat-resistant primers & inorganic zinc-rich primers to protect the underlying heat-resistant coating 4. Superior anti-rust performance on repeatedly heated systems 5. Effectively protects the base anti-corrosion layer and extends system service life 6. Good moisture resistance under hot-cold alternating environments 7. Certain colors may fade at high temperatures, but this will not affect the coating film’s physical properties ## Specification Data - Color: Silver Grey or other custom colors (silver grade resists up to 600°C; heat resistance varies by other shades) - Specific Gravity: ≥1.4 Kg/L (mixed paint) - Viscosity: ≥70 KU (mixed paint, 25°C) - Drying Time - Tack-free: Within 30 mins (25°C) - Hard dry: Within 4 hours - Full cure: 7 days standing at ambient temperature (ready for service) - Film Thickness: Wet film 78~223 μm, Dry film 35~100 μm - Recommended Total DFT: 70 μm (2 coats total) - Theoretical Coverage: 48.4 ㎡/Gal, 12.8 ㎡/L, 8.5 ㎡/kg (at 35μm dry film) - Recoating Interval: Min. 4 hours (25°C), no maximum recoating time limit - Volume Solids: 42 ±3% - Pot Life: 8 hours at 25°C / 5 hours at 40°C - Mix Ratio: Base : Hardener = 5.1 : 0.04 (by weight, varies by color) - Thinner: No.1005 Thinner 1564X - Thinner Dosage: 5 ~10% - Storage Stability: Minimum 18 months under normal storage ## Application Methods Brush Coating, Airless Spray, Conventional Spray ## Construction Precautions ⚠️ 1. Thoroughly remove grease, moisture, dust, rust and other contaminants from substrate surfaces before coating. 2. This heat-resistant topcoat shall be applied over primed substrates with No.1566, 1567, 1568, IZ-01 or equivalent heat-resistant primer & inorganic zinc-rich primer to extend system service life. 3. Product may separate after long-term storage; stir fully before use. 4. Avoid construction during rain or when relative humidity exceeds 85%RH. Fully dry damp substrates prior to coating. ## Note All data provided in this product datasheet are derived from internal laboratory test data for construction design reference only.
