1,3,5,7-Tetramethylcyclotetrasiloxane Silway D4H


  Silway D4H is a kind of active siloxane with Si-H bond, which can make addition reaction with unsaturate olefin.

Comparing with line chain polymethylhydrosiloxane, Silway D4H has better properties including lower impurity, higher purity, more fixed chain, and better design for modifided molecular.

Silway D4H is used for preparation of methylhydrosiloxane which needs certain hydrogen or linker chains, and polysiloxane which needs modified functional group.

Typical Application

• Preparation of various specific hydrogen contents and the number of links required for polymethylhydrogensiloxane

• Crosslinker of RTV and ALSR

• Synthetize high-quality side-chain siloxanes

• Good ingredient for optoelectronic materials


• High purity

• Contains fixed chain

• Good design for modified molecular
