Silicone Sealant

     Due to its special molecular structure, silicone sealant has the molecular structure of both inorganic and organic polymers. Silicone gum's gum is a polymer with Si-O as the main chain. The bond energy is 106 Kcal/mol, and the general polymer materials have small CO and CC bond energies of 80 and 85.2 cal/mol, in other words, if the Si-O bond is broken, high energy is inevitably required. Therefore, the silicone adhesive is stable, has superior UV resistance, ozone resistance, weathering resistance, temperature resistance and single-component, two-component applications in various forms, and can be manufactured according to the needs of the building of different performance requirements of the product In particular, in the structural bonding application of hidden glass curtain walls, other materials are irreplaceable. And China's raw material industry in the production of silicone sealant relative polysulfide, polyurethane to large-scale and mature, the current silicone sealant products accounted for more than 60% of the construction sealant usage in China. Foreign modified silicone products are also used in construction. At present, our country is limited to other fields.
