Vinyltriacetoxysilane and DOWSIL Z-6075

Vinyltriacetoxysilane is a clear liquid with an acrid vinegar odor. When it comes in contact with moisture, it hydrolyzes and forms silanols, which are chemical compounds that bind to inorganic substrates. In this article, we will discuss the differences between these two compounds. For more information, please consult the links provided below.

INNO SPECIALTY CHEMICALS is Triacetoxy(vinyl)silane (CAS:4130-08-9) manufacturer and Vinyltriacetoxysilane supplier in China, equivalent product are GENIOSIL GF 62 and DOWSIL Z-6075,contact us for more information.

Vinyltriacetoxysilane

Vinyltriacetoxysilane (VTAS) is a clear, acidic liquid that has a slight odor of vinegar. The substance reacts with moisture to form silanols, which can bind inorganic substrates and hydrolyze. Hence, it is used as a crosslinker in moisture-curing RTV silicone rubbers.

DOWSIL Z-6075

VTS is an acetoxy silane and is a crosslinker for moisture-curing RTV silicone rubbers. It can also serve as an adhesion promoter and coupling agent. It can be used to coat inorganic fillers. It should be stored in a dry, well-ventilated area. It can be harmful to the environment if stored in a wet area.

Crosslinker for RTV silicone rubbers

Vinyltriacetoxysilane (VTAS) is an acetoxy silane, a chemically reactive compound used as a moisture-curing crosslinker in RTV silicone rubbers. VTAS is also used as a coupling agent, adhesion promoter, and surface modification of inorganic fillers. Vinyltriacetoxysilane should be stored in a cool, dry place, protected from excessive humidity.

Polydimethylsiloxane is a diblock copolymer of siloxane. The hydroxyl-terminated polymer contains about 0.1% OH Si. The polydiorganosiloxan mixture contains vinyltriacetoxysilane and DOWSIL Z-6075 crosslinker, respectively.

The process for preparing these materials involves several steps. The first step is to select the catalyst. Titanium chelates can be used in place of DOWSIL Z-6075. Titanium chelate is an organic solvent and will accelerate the reaction. The catalysts used are usually incompatible with polydimethyl siloxan and vinyltriacetoxysilane.
