silica gel is the methyl room temperature vulcanized silicone rubber modified varieties, which is head by the hydroxy polydimethylsiloxane (107 gel) and methyl triethoxysilane oligomers (molecular weight 3 to 5) copolymer. In dibutyl tin dilaurate catalyst, polydimethylsiloxane and poly hydroxyl in the methyl triethoxysilane in the three-ethoxy Condensation polymer structure, the elastic after curing to the body than methyl RTV silicone rubber with high mechanical strength and adhesion, in a 70 ~ 200 ℃ temperature range of long-term use.
     silica gel shock, moisture, waterproof, breathable, resistant to ozone, weathering resistance, resistance to weak acid weak base properties. It is a very good electrical insulation properties, but also has good adhesion and low cost. Therefore, can be used in potting, coating, die, mold release, the release of drug delivery and other occasions. Plastic block at room temperature with methyl encapsulated electronic components are shock, moisture, sealing, insulation, stability, the role of various parameters. Room temperature, the methyl-block rubber coating directly to the speaker, it can be to reduce and eliminate the points the speaker frequency, the resonant frequency of loudspeaker performance after curing can be reduced about 20 Hertz. In the methyl compound at room temperature with the block into a certain amount of additives used as anti-adhesive paper. In the food industry, candy, cookies on the conveyor belt coated with a thin layer of methyl rubber block at room temperature, it can improve the anti-sticking properties of canvas, thereby improving the appearance of food, improve the utilization of raw materials.
       Block at room temperature in methyl adding some glue fumed silica, can be used to install the window glass, curtain walls, window frames, prefabricated panel joints, expansion joints runway. In addition, computer memory can be done in the core and the template adhesives, conductive silicon rubber and can do non-conductive silicone rubber adhesives. Treatment with silica gel can improve the fabric hand fabric, soft and resistant to wear of the song.
