MQ resin and six by the TEOS hydrolysis of dimethyl ether balance of silicon made. Reinforcement is mainly used for preparation of transparent liquid silicone rubber, silicone adhesive and silicone screen printing ink. The molar mass is generally 100-8000g/mol, the molecular structure of M and Q chain chain ratio and M the amount of the structural nature of the decision resin applications.
Grade XB-2051 XB-2052 (toluene)
Appearance colorless transparent liquid White powder
Solid content (%) 100 60
Viscosity (mpa.s) / 20 ~ 40
M / Q value is 0.6 ~ 0.9 0.6 ~ 0.9
Toluene insoluble content (%) ≤ 0.5 full solution
XB-2051: the MQ resin powder is completely dissolved in toluene, xylene, heptane and other solvents, before use cloth to filter out recommended mechanical impurities that may exist and, if large pieces of solid proposals to speed up the dissolution of crushed before use. Inhalation of resin solution while stirring to the base oil, charging is completed, heated to 180 ~ 190 ℃, low-high vacuum until almost no low molecular weight off so far. Or directly to the resin powder added to the base oil, with the three-roll mill roll grinding to a completely decentralized.
XB-2052: inhalation of resin solution while stirring to the base oil, charging is completed, heated to 180 ~ 190 ℃, low-high vacuum until almost no low molecular weight off so far.
◎ surface treatment agent: As used in silicone pressure-sensitive adhesive, the phone keypad, epoxy adhesive surface.
◎ Tim reinforcing material: plastic can be used for RTV, HTV rubber, add liquid silicone rubber, heat curing silicone rubber compound, shell encapsulating semiconductor components.
◎ Adhesive: For construction sealant, organic resin coating.
◎ Other additives: such as the preparation of release agent, defoamer, anti-sticking agent and brightener, plus forming anti-adhesive peel strength modifier.
200kg, 50kg, 25kg plastic barrel.
