Poly(methylhydrosiloxane) is widely used as a crosslinking agent in silicone rubber and resin formulations. It plays a critical role in the production of high-performance elastomers, providing thermal stability and flexibility. In coatings, it enhances water repellency and durability, making it suitable for protective layers on various surfaces. Additionally, it is utilized in the synthesis of adhesives and sealants, where it improves bonding strength and resistance to environmental factors. In the electronics industry, it serves as a dielectric material in insulating components. Its hydrosilylation properties also make it valuable in organic synthesis for creating silicon-based compounds.
