Description

Product: Methyl MQ Silicone Resin
Other names: Methyl MQ Silicons Resin, MQ Resin
CAS No.: 68988-56-7

Methyl MQ silicone resin is a type of silicone resin with a unique structure. It is a three-dimensional spherical structure silicone resin generated by the co hydrolysis condensation reaction of organosilicon compounds containing tetrafunctional siloxane chains (SiO4/2, Q) and organosilicon compounds containing monofunctional siloxane chains (R3SiO1/2, M). Its molar mass is generally between 1000 and 8000 g/mol, and it is in a viscous fluid to solid powder state. It is hard and brittle, with a wide range of glass transition temperatures (Tg). It is generally believed that MQ silicone resin is a dense sphere with a two-layer structure, with a high-density cage like SiO2 core connected by Si-O chains, a polymerization degree of 15-50, and a lower density R3SiO1/2 shell.

Applications:
1. Used as a thickening agent for organic silicon pressure-sensitive adhesives;
2. Produce high-temperature resistant coatings for insulation, bonding, sealing, etc. of H-grade motors;
3. As a reinforcing additive in condensed liquid silicone rubber, the reinforced silicone rubber is colorless and transparent, with high mechanical strength;
4. It can be used to make waterproof paint, such as lipstick for daily chemical industry;
5. It can be used as raw materials for release agent;
6. As a basic raw material added to defoamers, it can improve their defoaming and anti-foaming abilities.
