Methyl MQ silicone resin TPD-MQ102 is a new type of organosilicon material with three-dimensional (nonlinear) structure composed of its molecules with Si-O bond as skeleton. Its structural formula: [(CH3)3SiO1/2]a[SiO4/2]b, in which [(CH3)3SiO1/2] is called M and [SiO4/2] is called Q. With different ratio of M and Q, and their properties, specifications and applications show different.
