Room temperature vulcanized silicone rubber can be divided into single-component and two-component room temperature vulcanized silicone rubber according to its packaging method, and can be divided into condensation type and addition molding according to the vulcanization mechanism. Therefore, room temperature vulcanization silicone rubber can be divided into three types according to the composition, vulcanization mechanism and use process, namely, one-component room temperature vulcanization silicone rubber, two-component condensation type room temperature vulcanization silicone rubber and two-component addition type room temperature vulcanization silicone rubber .
