It is mainly composed of adhesive and heat conducting particles. Before sizing, it is a paste like mixture. After sizing, it solidifies under certain time and conditions. Our heat-conducting silica gel is a one component room temperature vulcanized silicone rubber, which has a good bonding effect. Room temperature curing, simple curing conditions, repairable, curing thickness generally between 4-5mm. However, it is sensitive to the surface state of the radiator, and the binding force of the surface polluted device or radiator is weak. Strict on-site process control.
1. Environmental protection, non-toxic, non corrosive, in line with RoHS and reach instructions.
2. Excellent adhesion, fixation, insulation, sealing, moisture-proof, shockproof and aging resistance.
3. It can be firmly bonded with metal, glass, ceramic, plastic and other materials.
4. The cured silicone rubber has good electrical insulation performance, high and low temperature resistance, water and moisture resistance, aging resistance and long-term rubber elasticity.
