Silicone resin is a thermosetting polysiloxane system with high crosslinking structure. silicon-oxygen bond has higher bond energy, so polysiloxane has high thermal stability. It has excellent heat resistance and weather resistance, and has excellent electrical insulation, chemical resistance, hydrophobicity and flame retardancy, and other properties can be obtained by modification.
In very long a period of time, the silicone resin was mainly used as electrical insulating paint and coating. Polysiloxane combines organic polymers and inorganic polymers with excellent surfactants, heat and cold resistance, aging resistance and UV resistance, non-toxic and physiological inert, and thus used as cosmetic ingredients additives.
