Used as a crosslinking agent in silicone curing systems, especially in addition-cure silicones for encapsulation and molding. Provides flexibility and thermal stability in silicone rubbers. Acts as a hydride donor in catalytic hydrosilylation reactions, useful in synthesizing functional silicones. Employed in coatings and release agents due to water repellency and low surface tension. Also utilized in personal care products for smooth feel and film formation.
