1. Performance characteristics

MQ silicone resin is a very unique type of polysiloxane, and water glass is the main raw material which is cheap and easy to obtain. The wide range of uses makes it a promising new type of organosilicon polymer compound. MQ silicone resin is a kind of silicone resin composed of monofunctional Si-O unit (M unit) and tetrafunctional Si-O unit (SiQZ referred to as Q unit). Generally, MQ silicone resin is a powder, and it is not easy to disperse when used directly. It has the characteristics of heat resistance, film formation, adhesion, water repellency, aging resistance, and ultraviolet radiation resistance.

2. Scope of application

1. Make high temperature coatings for insulation, bonding and sealing of H-class motors.
2. It can be used to make various waterproof coatings, and it is an ideal material for the daily chemical industry to make lipsticks, etc.
3. It can be used to make release agent of various materials.
4. As a basic raw material, it can be added to the defoaming agent, which can improve the defoaming and anti-foaming ability.
5. Improve and adjust the peeling force of pressure-sensitive adhesives, used to make pressure-sensitive adhesive tapes, etc.
6. Reinforcing filler: can be used for RTV glue, HTV glue, addition type liquid silicone rubber, hot vulcanized silicone rubber compound, shellless encapsulation of semiconductor components

3. Application prospects

MQ silicone resin has great industrial application value. First of all, it is the only type of organosilicon polymer compound that does not start from expensive raw materials such as organosilicon metal compounds and silicon, but actually starts from water glass for mass production.
At the same time, practical progress has been made in introducing various organic groups into methyl MQ silicone resins or extending them into silicone resins with MDQ or MTQ structures. For example, epoxy-modified MQ silicone resin can be used as an adhesive surface treatment agent for tackifiers of organic resin coatings; chloromethyl-modified MQ silicone resin is sensitive to ultraviolet rays, electron beams and X-rays; high alkyl modified MQ silicone resin can be used as an additive for organic resins to reduce its internal stress and as an internal mold release agent.
In addition, in recent years, the consumption of silicone resin in the electronics/electrical industry has grown rapidly, which is also an important driving force for the development of global silicone resin in the future, and the market prospect is very broad.
