Poly(methylhydrosiloxane) is widely used as a cross-linking agent in silicone-based formulations, particularly in the production of silicone rubbers and resins. It plays a key role in hydrosilylation reactions, where it helps create durable, heat-resistant, and flexible silicone products. This chemical is also employed as a water repellent in coatings for textiles, paper, and construction materials, enhancing their resistance to moisture. In the personal care industry, it is utilized in hair and skin care products to provide a smooth, non-greasy feel and improve spreadability. Additionally, it serves as an anti-foaming agent in industrial processes, such as oil refining and food production, to control foam formation. Its versatility and stability make it valuable in various applications across multiple industries.
