RTV can be divided into three types according to its composition, curing mechanism and application process:1K RTV silicone rubber, 2K condensation-type RTV silicone rubber and 2K addition-type RTV silicone rubber. The largest consumer area of RTV silicone rubber is the construction industry, and the other major application area is the automotive industry. In addition, in electronic power, renewable energy and other manufacturing, RTV silicone rubber is widely used in packaging, adhesive and other fields.
