Characteristics Of Silicone Glue

Silicone glue is a kind of silicone rubber used in silicone and silica gel, silicone and similar plastic bonding adhesive, depending on the contact is bonded or by the surface of the seal or water molecules in the air curing. Silicone glue according to its nature, raw materials are different, can be divided into room temperature bonding and high-temperature bonding, the main ingredient is silicone, crosslinking agent. 2 classification Silicone Glue according to its chemical properties can be divided into organic silicone glue and inorganic silicone glue. Organic silicone glue has high and low temperature resistance, electrical insulation, oxidation stability, weather resistance, refractory, hydrophobic, corrosion-resistant, non-toxic tasteless and physiological inertia and other outstanding characteristics, widely used in aerospace, electrical and electronic, construction, transportation, chemical, textile, food, light industry, medical and other industries. Inorganic silicone glue with strong adsorption can quickly and effectively absorb the water in the sealed package, chemical property stable, non-toxic harmless characteristics, widely used in food, packaging industry. 3 Product Description Silicone glue is a kind of silicone rubber used in a variety of items, depending on the contact is bonded or by the surface of the seal or water molecules in the air curing. Dry cold environment in the curing speed may be very slow, but the appropriate environment, such as 25 degrees Celsius more than 65% relative humidity, this type of glue can be dry in 3-30 minutes (finger), general curing time for the table dry 10-20 minutes. Full curing takes 24 hours. After curing the elastomer properties and silica gel, bonding strength can reach the silica gel itself, is the silicone seal ring and Japanese-style hollow tube, such as the formation of a good silicone bonding adhesive. 4 application range is mainly used for bonding between silicone and silica gel, silicone rubber and plastic, metal (such as copper, aluminum, iron, stone, bamboo, etc.) between the bonding, the product has a high transparency, good oil performance, acid and alkali resistance, good adhesion, easy to operate and so on. 5 Chemical principle Silicone glue is a kind of high activity adsorption material, belongs to amorphous substance, its chemical formula is Msio2 NH2O. Insoluble in water and any solvent, non-toxic tasteless, chemical property stability, in addition to strong alkali, hydrofluoric acid and no reaction with any matter. Various types of silicone glue form different micro-pore structures because of their different manufacturing methods. The chemical composition and physical structure of silicone glue determines that it has many other similar materials that are difficult to replace: high adsorption performance, good thermal stability, stable chemical properties, high mechanical strength, etc.
