Adhesive manufacturer, room temperature vulcanized silicone 123
Electronic silicone manufacturerAs a neutral curing chemical for oxime removal, DM room temperature vulcanized silicone and sealant are basically odorless. In cross-linking reactions, they do not release any unpleasant or pungent curing by-products, such as acids. These non corrosive silicone adhesives/sealants can be used for electrical, electronic, and mechanical bonding and sealing, without causing any fading or corrosion of sensitive metals. Room temperature vulcanized silicone can form a strong, tough, flexible, and elastic rubber like material with good chemical and high temperature resistance, maintaining flexibility at low temperatures and stability at high temperatures.
It can resist aging, weathering and thermal cycle without hardening, shrinkage or cracking. Room temperature vulcanized silicone can be used for bonding/sealing, gaskets, and insulation of various industrial products, including metal and glass structures, automobiles, ships, mechanical engineering, machine tools, maintenance, electrical/electronics, aerospace, and consumer goods. Instructions for use: When using vulcanized silicone, in order to achieve optimal performance, the bonding surface must be clean and free of any contaminants such as dirt, oil stains, lubricants, and any substances previously applied.
For cleaning glass and plastic, we recommend using DM.9195 cleaner. For metal, DM.9190 cleaner should be used. If mechanical pretreatment such as grinding, sanding, sandblasting, etc. can be carried out, it will greatly optimize the adhesion surface. When bonding elastomers, the original talc layer should be removed. These vulcanized silicone products are packaged in simple 200m pressure tanks or 310m waterproof pipe shells.
The adhesive sealant can be directly extruded from the pressure tank onto the surface to be joined, without the need for an additional gluing device. After use, immediately seal the nozzle with the matching lid to prevent the adhesive sealant inside the container from hardening. Waterproof pipe casing is suitable for a wider range of applications. Glue can be applied manually or with a pneumatic glue gun. After being exposed to air, the product will immediately begin the curing process. Therefore, the parts should be assembled before the silicone is still damp and has not formed a skin. The curing mechanism of single component RTV (room temperature vulcanization) silicone adhesives and sealants can be cured at room temperature under the influence of moisture in the air.
The curing speed depends on the relative humidity and temperature in the environment. DM, Room temperature vulcanized silicone gel cures relatively quickly, generally forming a skin within minutes. It does not stick to hands when touched within a few minutes to several hours, and forms an elastic rubber body within about 24 hours. At a temperature of 23 ° C and a relative humidity of 50%, the curing rate is 2mm. Due to the fact that single component systems rely on moisture diffusing into the air inside the sealant for curing, it is generally not recommended to use this product when a depth of curing greater than 10-15mm is required to ensure that moisture can diffuse and react with the central part of the bonded component.
High temperature and high humidity can accelerate the curing process; Low temperature and low humidity can slow down the curing process. Resistance DM, “RTV silica gel has good temperature resistance, oil resistance, and anti-aging ability, and shows excellent weather resistance and Uv resistance. In continuous operation, these products are used at temperatures ranging from -60 ° C to+260 ° C and can be used at high temperatures of+315 ° C (DM, 3020 can withstand high temperatures of+370 ° C) in the short term. Storage and shelf life: Store the product in an unopened container in a cool and dry environment.
