Silicone gel, belonging to the addition curing type, consists of A and B double group curing. Vinyl dimethylsiloxane is one of the main components of additive silicone gel. Under the catalysis of organic platinum, the silicone gel is formed by addition reaction with hydrogen-containing polysiloxane.

Silicone gel products are non-corrosive and have excellent electrical properties, low temperature resistance (-50 ° C) and water and moisture resistance. Due to its soft properties, silicone gel is not only dustproof and moisture-proof when used for potting protection of electronic parts, but also can well reduce external impact to protect internal components and reduce damage, which is widely used in the medical industry, electronic and electrical industry, automotive industry and other fields. When the silicone gel is used for sealing casting, only a small gap is left for the poured product to flow through, so the silicone condensate needs to have good fluidity. In the prior art, the silicone gel has poor flow performance, which is prone to the problem of inadequate filling leading to poor sealing performance. When it is used for potting electronic devices, it needs to be subjected to the force exerted on it by other objects after curing. In order to ensure that the sealing performance does not change, it needs to have good flexibility.
