Condensed room temperature vulcanized silicone rubber is characterized by the condensation reaction between silicone hydroxyl groups and other active substances, which can crosslink into elastomers at room temperature. The product is divided into two forms: single component packaging and two-component packaging. Single component room temperature vulcanized silicone rubber (RTV-1 rubber for short) is one of the main products in condensed liquid silicone rubber. Usually formulated from basic polymers, crosslinking agents, catalysts, fillers, and additives. The product is packaged in a sealed hose and can be extruded during use. When in contact with air, it can self vulcanize into an elastic body, making it extremely convenient to use. Vulcanized rubber can be used for a long time in the temperature range of -60~+200 ℃, with excellent electrical insulation performance and chemical stability. It can withstand water, ozone, climate aging, and has good adhesion to various metal and non-metal materials. Mainly used for coating various electronic components and electrical equipment, the packaging material serves as insulation, moisture-proof, and shockproof; As a surface protective material for semiconductor devices; It can also be used as a sealing filler and elastic adhesive.
One of the typical applications of silicone sealant is glass curtain walls. The glass and aluminum alloy frame are bonded with organic silicon structural adhesive as the exterior wall material, and the expansion joints are sealed with organic silicon weather resistant adhesive for waterproofing. Other applications include peripheral sealing for aluminum alloy doors and windows and plastic steel doors and windows, sealing for glass installation and moving slots, sealing with rivets and fixing screws, and waterproofing sealing between sanitary ware and countertops, walls, and furniture in kitchens, bathrooms, and bathrooms; Sealing of aquariums, canopies, metal roofs, display windows, counters, wall panels, and color steel plates; Used for waterproof joint sealing between high-grade highway sections.
