Processing Customized High Transparent Jelly Silicon Gel PCB Circuit Board Protection Shockproof Repairable Electronic Silicon Gel
Characteristic
1. Stable physical and chemical properties, with a wide temperature resistance of -60~230 ℃;
2. Low viscosity, easy to use, no solid fillers, fully transparent, and easy to observe sealing components;
3. Capable of repeated operation, repairability, high flexibility, and extremely low shrinkage rate;
4. Good dust-proof, moisture-proof, shockproof, insulation, and other performance;
5. After solidification, the surface becomes naturally sticky, enhancing the physical adhesion of most substrates without the need for a primer;
6. It can be cured at room temperature or by heating, with the characteristic of faster curing at higher temperatures, and the curing time can be freely controlled;
Product Description:
This product is a very soft, low cross-linking density addition silicone rubber. It is a low-viscosity liquid before vulcanization. After vulcanization, in addition to the general characteristics of addition silicone rubber, it has good shock absorption, moisture resistance and sealing due to its soft nature. properties and excellent dielectric insulation properties over a wide range of temperature and humidity.
Product Features:
1. Medium temperature curing, the curing time can be adjusted according to different temperatures;
2. It is low-viscosity silicone oil before curing and gel elastomer after curing.
