Application

Polysiloxanes di-Me hydrogen-terminated serve a versatile role as an essential component in various industrial and consumer applications. Functioning primarily as a hydride terminated form of polydimethylsiloxane, these organosilicon compounds are employed for their surfactant and antifoaming properties. They are integral as active silicone fluids in automotive viscous limited slip differentials and couplings. In the innovative field of soft lithography, they find use as stamp resins. Additionally, as an antifoaming and carminative agent, they are frequently integrated into over-the-counter medications, as well as skin care and beauty products, where they help to create a moisturizing barrier that minimizes water loss. The solubility of these compounds in various organic solvents, such as aromatic and petroleum hydrocarbons, enhances their utility as organic silicon intermediates and blocking agents. Furthermore, their reactive Si-H groups enable them to participate in the hydrosilylation process for the synthesis of copolymer macromolecules, leading to the development of a variety of reactive silicone oils.
