Tetramethylcyclotetrasiloxane D4H CAS No.2370-88-9

D4H is an active siloxane containing Si-H bonds which can react with unsaturated olefin Si-H. It can be used to prepare various kinds of polymethylhydrogen siloxane with specific hydrogen content and required chain number and functional group modified polysiloxane. Special hydrogen can be used as a crosslinking agent for liquid silicone rubber. Synthesis of side chain polysiloxane liquid crystal polymer and various functional side chain modified silicone oil. The high purity tetramethylcyclotetrasiloxane can also be used in the electronic industry as a precursor of plasma vapor deposition to form silicon dioxide and silicon carbide insulating films
