Silica gel is mainly divided into RTV Silica gel, high-temperature vulcanized Silicone

Introduction and classification of RTV Silicone rubber

RTV Silicone Rubber (RTV) is the advent of the 60 's a new type of silicone elastomer, the most notable feature of this kind of rubbers is at room temperature without heating, the normal pressure can be cured in situ, the use of extremely convenient. As a result, the advent of the rapid emergence of the entire silicone products an important component. Now RTV silicone rubber has been widely used as adhesives, sealants, protective coatings, potting and molding materials, in all walks of life have its use.

RTV Silicone Rubber According to its packaging method can be divided into one-component and two-component RTV silicone rubber, according to the vulcanization mechanism can be divided into condensation type and addition molding. Therefore, RTV silicone rubber According to the composition, vulcanization mechanism and the use of different technology can be divided into three types, namely, single component RTV silicone, two-component condensation RTV silicone and two-component RTV Silicone rubber. The three series of RTV Silicone rubber has its own characteristics: one-component RTV Silicone rubber is easy to use, but the deep curing speed is difficult; The advantages of two-component RTV Silicone rubber are not exothermic when cured, shrinkage is very small, no expansion, no internal stress, curing can be carried out at the same time in the interior and surface, can be deep vulcanization; the vulcanization time of RTV Silicone rubber is mainly determined by temperature, so the curing rate can be controlled by temperature adjustment.
