Vinyltrimethoxysilane

Technical Data

Reactivity: In the presence of moisture the methoxy groups of VANABIO® VS6611 hydrolyze to produce methanol and reactive silanol (Si-OH) groups which can bond to a variety of inorganic substrates or react with each other to form siloxane bonds (Si-O-Si). The organophilic vinyl end of VANABIO® VS6611 can also react with a suitable polymer (activated by peroxide or radiation).

Application

• VANABIO® VS6611 is suitable for the preparation of moisture-curing polymers, e.g. polyethylene. Silane crosslinked polyethylene is widely used as cable isolation, and sheathing mainly in low voltage applications as well as for hot water/sanitary silicone pipes and underfloor heating.

• VANABIO® VS6611 is used as a co-monomer for the preparation of different polymers such as polyethylene or acrylics. Those polymers show an improved adhesion to inorganic surfaces and they can also be crosslinked with moisture.

• VANABIO® VS6611 is used as an efficient adhesion promoter for various mineral-filled polymers, improving mechanical and electrical properties especially after exposure to moisture.

• VANABIO® VS6611 is used to improve the compatibility of fillers with silicone polymers, leading to a better dispersibility, reduced melt viscosity and easier processing of filled plastics.

• VANABIO® VS6611 is used to pretreat of glass, metals, or ceramic surfaces, improve the adhesion of coatings on these surfaces and corrosion resistance.

• VANABIO® VS6611 is used as moisture scavenger. VANABIO® VS6611 reacts rapidly with water. This effect is used widely in sealants.

Packing and Storage

• VANABIO® VS6611 vinyltrimethoxysilane is supplied in 190Kg steel drum or 950Kg IBC container.

• In the unopened original container VANABIO® VS6611 (VTMO silane, CAS 2768-02-7) has a shelf life of one year in a dry and cool place.
