Silicone MQ resin is formedby a branched, cage-like oligosiloxane, in which the core is composed by siloxane monomeric unit SiO4/2 (called Q) and outer layer is composed by non reactive substituents such as Me3SiO (called M). Silicone MQ resin is available in form of white powders or flakes. Besides containing Si-OH, the resin may contain other functional groups.
