Organic Silicone High Thermal Conductivity Encapsulating With Silicon For LED Thermal Cycle
GF High thermal conductivity silicon encapsulating gum is a room temperature/heating curing and molding organic silicone materials. This kind of two-component elastic silicone potting, designed to protect in harsh conditions of electronic products. High thermal conductivity silicon encapsulating glue used new technology without heating, would be curing. When used according to 1:1 (weight ratio or the volume in the thorough mixing proportion of A and B two components, products will be in A certain time, form of the elasticity of curing buffer material.
Thermally Conductive Encapsulant is a low-viscosity two-component silicone potting material. This product has good fluidity, does not produce small molecules during curing, has excellent thermal conductivity and insulation properties after curing, and has no corrosion to various substrates. It is mainly used for potting of electronic components and circuit boards, such as driving power supplies. Sensors, photovoltaic junction boxes, etc., provide protection for electrical/electronic devices and components under severe conditions such as high humidity, extreme temperature, thermal cycle stress, mechanical shock and vibration, mold, dirt, etc., no contact thermal resistance, seamless contact Heat-generating electronic components, heat is conducted from the separation device or the entire PCB to the metal shell or diffusion plate, thereby improving the efficiency and service life of the heat-generating electronic components.
