HN-8820 Thermally Conductive Silicone Potting Compound – 2.0 W/m·K, V-0 Flame Retardant
Product Description
HN-8820 Thermally Conductive Silicone Potting Compound – 2.0 W/m·K, V-0 Flame Retardant
-
Product Overview
HN-8820 is a two-component, addition-cure RTV silicone potting compound with a 1:1 mixing ratio. It features low viscosity, excellent thermal conductivity (2.0 W/m·K), and high fluidity, making it ideal for protecting sensitive electronic components. It cures at room temperature or with heat, maintaining rubber elasticity across a wide temperature range from -40°C to 150°C. With superior insulation, waterproof, anti-aging, and flame-retardant properties, it ensures long-term reliability in demanding environments.
