GOMIN High-Temperature Coating Series
Engineered for Extreme Heat: 400°C to 800°C Premium Thermal Protection with 1500°C Short-Term Limit
Product Overview
The GOMIN High-Temperature Coating Series represents the pinnacle of thermal protection technology, engineered by Dalian Gomin Special Coating Co., Ltd. for extreme-heat industrial applications. This comprehensive series features two specialized formulations — GM-3040 (Water-based High-Temperature Pure Silicone Resin Coating) and GM-3041 (Water-based High-Temperature Heavy Anti-Corrosion Paint) — designed to deliver uncompromising performance in the most demanding thermal environments.
The GM-3040 formulation utilizes advanced pure silicone resin technology to achieve long-term temperature resistance up to 800°C on metal substrates, with a short-term limit of 1500°C. Its water-based, eco-friendly composition contains no toluene or xylene, meeting stringent environmental regulations while providing a 20-30 year comprehensive protection lifespan.
The GM-3041 variant is a two-component heavy anti-corrosion system engineered for aggressive chemical and thermal environments. Operating across a temperature range of -20°C to 600°C, it combines exceptional acid-alkali resistance with 2000-hour salt spray protection, making it the ideal solution for chemical processing facilities, power plants, and energy infrastructure.
Key Features & Advantages
Extreme Temperature Resistance
GM-3040 withstands continuous temperatures up to 800°C with a short-term limit of 1500°C. GM-3041 operates from -20°C to 600°C, providing year-round thermal protection across cryogenic to high-heat conditions.
Eco-Friendly Water-Based Formula
Both formulations are water-based with zero toluene and xylene content, low odor, and full compliance with modern environmental regulations. Safe for indoor and outdoor application without harmful VOC emissions.
Superior Hardness & Adhesion
GM-3040 achieves 4-5H pencil hardness with Grade 0 adhesion (cross-hatch test). GM-3041 delivers 5H Mohs hardness with Grade 0 adhesion (cross-cut tape method), ensuring long-lasting mechanical protection.
Exceptional Corrosion Resistance
GM-3041 withstands 2000 hours of salt spray (5% NaCl) with no change, and 365 days of immersion in 30% sulfuric acid and nitric acid without degradation. GM-3040 provides excellent long-term anti-corrosion and anti-yellowing performance.
Versatile Application Methods
GM-3040 is optimized for spray application with water dilution (5-10%). GM-3041 supports spray, brush, and roller application, offering flexibility across different project requirements and substrate geometries.
