High Peel Strength Pressure Sensitive Adhesive (PSA) Me-Silicone Resin MQ Trimethylsiloxysilicate

MQ silicone resin has a SiO4/2 polymer core (i.e. Q) and a trimethylsiloxy (i.e. M) periphery, which forms a compact two-layer cell structure of silicone resin. In addition to the Si-OH group, it may contain other active groups. Methyl silicone resin MQ has a trimethyl end. When part of the methyl group in MQ resin is replaced by Vi group, it is called methyl vinyl silicone resin MQ. When part of the methyl in MQ resin is replaced by Me2HSiO group, it becomes hydrogen-containing silicone resin MQ.

With such a special molecular structure, MQ silicone resin is easily dissolved in toluene, xylene and other organic solvents. The solution is transparent and colorless, has good mechanical properties, insulation, moisture and water resistance, and resistance to low and high temperatures. The most important application of methyl MQ resin is as the main raw material for the production of pressure sensitive silicone adhesive (PSA), as an additive in the production of personal protective equipment, wear-resistant coating, paint, defoamer, etc. MQ vinyl silicone resin is used as a reinforcing filler in adhesive silicone rubber, transparent silicone rubber, sealant, LED packaging material, etc.
