BX-SRS-503 Smokeless silicone resin
This Smokeless silicone resin is a next-generation organic silicone resin. It is synthesized from methyl monomer, phenyl monomer, and specialized silane monomers using an advanced proprietary technology. It has good activity, high hardness, anti after-tack in hot state, small loss of light, hot smoke and other properties. It can be used as the base resin to prepare heat resistant coatings for ovens, baking pans and household appliances, can also be used for mica plate sticking agent, magnesium oxide powder moisture-proof treatment agent.
Ⅰ. Product Details

| Heat resistance (Varnish: float type aluminum powder=4:1, 500±10℃, 3h) | No peeling, no cracking, no blistering |
| Note: The above data are for reference only and are not guaranteed technical specifications. *Corrections & Supplementary Explanations: 1. Corrected “Surface drying” to “Surface drying” (standard terminology for drying stage description); 2. “Opalescent light is allowed” means the liquid may show a faint iridescent or milky sheen—this is a normal and acceptable characteristic in modified resin systems (e.g., silicone-modified acrylic resin) and does not indicate impurity or quality issues; 3. Viscosity (12-25S via 4# Cup at 25℃) represents medium viscosity, balancing easy application (e.g., brushing, rolling) and avoiding excessive fluidity that reduces film thickness; 4. “Solid content 50±1%” means non-volatile components (resin, functional additives) account for half the total mass, reducing solvent emissions while ensuring good film-forming continuity; 5. Drying time covers three scenarios: surface drying (2h, surface no longer tacky for initial handling), room-temperature complete drying (24h, full curing without heat), and heat-accelerated drying (180℃ for 1h, suitable for industrial efficient production); 6. Heat resistance requirement (500±10℃ for 3h, no defects) confirms the product is applicable to high-temperature environments (e.g., high-temperature equipment coatings, heat-resistant decorative layers). | |
