Application of room temperature vulcanization (RTV) silicone rubber
Room temperature vulcanization (RTV) silicone rubber is divided into two categories: one-component (RTV-1) and two-component (RTV-2) in terms of product form; in terms of vulcanization mechanism, it is divided into two systems: condensation type and addition type. . Various forms of room temperature vulcanized silicone rubber need to be reinforced with fillers to be useful. At present, fumed silica is the most used and most effective RTV silicone rubber reinforcing filler. Since RTV silicone rubber is generally used as a sealing material for pouring, caulking, coating, etc., in order to maintain the viscosity and fluidity before vulcanization, the amount of fumed silica is generally much less than that of high-temperature vulcanized silicone rubber, and it is often combined with other supplements. Strong and semi-reinforcing fillers are used together to facilitate construction operations.
