Two-component room temperature vulcanized silicone rubber (RTV-2 for short) is not as convenient to use as RTV-1, but its component ratio is rich in change. One variety can obtain vulcanized products of various specifications and properties, and it can also be deeply vulcanized. Therefore, it is widely used in electronic and electrical appliances, automobile, machinery, construction, textile, chemical industry, light industry, printing and other industries for insulation, packaging, caulking, sealing, moisture-proof, anti-seismic and the production of roller materials. In addition, because RTV-2 has excellent demodulation, it is widely used as soft mold material for the reproduction and manufacturing of cultural relics, handicrafts, toys, electronic appliances, mechanical parts, etc.


One of the typical applications of silicone sealant is glass curtain wall. The glass and aluminum alloy frame are bonded with organosilicon structural adhesive as external wall material, and the expansion joint is waterproof and sealed with organosilicon weathering adhesive. Other applications also include the surrounding sealing of aluminum alloy doors and Windows and plastic steel doors and Windows, the sealing of the patchwork, rivet and fixed screw of the glass installation and mobile groove: the waterproof sealing between the kitchen, bathroom and toilet sanitary ware and the table top, wall and furniture; Sealing of aquarium, ceiling, metal cover, window, counter, wall panel, color steel plate; Used for waterproofing caulking sealing between plates of high grade highway, etc.


In addition to building sealant, RTV also includes sealant materials for aerospace, nuclear power plant, electronics, machinery, automobile and other industries, silicone sealant for electronic components, silicone mold glue used as soft mold material, etc. These varieties are in relatively low demand, but are essential in many situations.
