As a type of silicone resin with a unique structure, MQ silicone resin is a silicone resin with a three-dimensional spherical structure formed by the co-hydrolysis-condensation reaction of organosilicon compounds containing tetrafunctional siloxane units (Q units) and organosilicon compounds containing monofunctional siloxane units (M units). Its molar mass typically ranges from 1,000 to 8,000 g/mol, and it presents various states from viscous fluids to solid powders. It is hard and brittle, with a relatively wide glass transition temperature (Tg) range.
