Silicone Gel Load Cell 1:1 Silicone Electrical Waterproofing Gel For PCB Junction Box
Product Description of Silicone Electrical Waterproofing Gel :
Electronic-grade silicone gel is a two-component, addition-curing polymeric material that, upon curing, exhibits exceptional softness and elasticity (resembling "jelly" to the touch). It features excellent electrical insulation properties, high and low-temperature resistance (ranging from -50°C to 250°C), and superior resistance to aging. Specifically designed for precision electronic components, it is primarily utilized for insulation protection, moisture and dust proofing, and stress buffering.
