Organic silicon materials have the properties of both organic and inorganic materials, and exhibit many unique physical and chemical properties, such as non-toxic and odorless, weather resistance, electrical insulation, oxidation resistance, low surface energy, biological inertness, flame retardant, and hydrophobicity. Widely used in national defense industry, energy development, light industrial food, textiles, electrical and electronic, machinery, construction, transportation, medical and pharmaceutical, daily life and other fields. At present, the core products of the silicone industry include silicone rubber, silicone oil, silane coupling agents and silicone resins. MQ silicone resin is a kind of silicone resin, which has a unique structure and excellent properties. It is mainly used as a surface treatment agent and tackifier for silicone pressure-sensitive adhesives, reinforcing fillers for silicone rubber, and silicone defoaming Agent, release agent, high temperature resistant coating, release agent, etc.
