silicone gel resin for shocking absorbing

silicone gel resin for shocking absorbing
SC-722 is a transparent odorless two-part silicone gel, specially designed to seal, protect and preserve the electrical characteristics of delicate electronic circuits in severe environments. It is suitable for batch processing or automated dispensing. It forms a self-healing, cushioning, resilient gel-like mass when mixed in an 1 to 1 ratio by weight or by volume. The cured gel develops much of the non-flow characteristics and dimensional stability of a solid elastomer and retains much of the stress relief and self-healing properties of a liquid as well. It has excellence in electrical properties, waterproof, fire resistance, and weather resistance. Those properties are not significantly affected by the changes of temperature. Its primary uses include seal of electronic devices, falsies, and cushioning potting.
