PMQ is a phenyl silicone resin formed through the co-hydrolytic condensation reaction of an organic silicone compound containing tetravalent siloxane segments (SiO4/2, Q) and an organic silicone compound containing monovalent siloxane segments (R3SiO1/2, M), resulting in a three-dimensional spherical structure.

Additionally, unlike commercial products, this product does not contain toluene.
