Appearance

Colorless transparent liquid

Specification

XJY-705 TMCTS / 1,3,5,7-Tetramethylcyclotetrasiloxane / D4H / 2,4,6,8-Tetramethylcyclotetrasiloxane is a reactive siloxane with Si-H bond and can react with unsaturated olefins.

 

Compared with linear hydrogen-containing siloxane, TMCTS has high purity because of fewer impurities; The chain links are fixed, so the molecular structure design is easy.

 

XJY-705 TMCTS (2370-88-9) has been registered (Full substance) under REACH (EC) 1907/2006.

Application

 

XJY-705 TMCTS can be applied to: 

1. prepare Polymethylhydrosiloxane and functional group-modified polysiloxane with specific hydrogen content and desired number of links.

2. used in special cross-linking for synthesizing room temperature vulcanized silicone rubber and addition liquid silicone agent.

3. used in synthetic special tackifiers.

4.TMCTS can synthesize various high-quality side-chain modified silicone oils such as epoxy silicone oil, polyether-modified silicone oil and alkyl modified silicone oil.

5. used in the gas required in the process of making semiconductor wafers.

6. 1,3,5,7-Tetramethylcyclotetrasiloxane (TMCTS) is a good impregnant for photoelectric materials. It is used in the production of silicone polymers and as a precursor for the deposition of polysiloxane, cyclic siloxane, silica and low dielectric constant carbon oxide films for microelectronics and semiconductors. TMCTS can also be used as a precursor for plasma vapor deposition in the electronic industry to form silicon dioxide and silicon carbide insulating films.
