Product Description

Chemical Name:  Vinyltrimethoxysilane 

Synonym:   (Trimethoxysilyl)ethylene;

             Ethenyltrimethoxysilane;

             Trimethoxy(vinyl)silane

CAS NO.:  2768-02-7

EINECS NO.:  220-49-8

Properties

Pipes and cables produced from silane-Crosslinked polyethylene (PE-Xb) using Silane OSi HIOSil VTMO are more resistant to heat and weathering than products made from non-crosslinked polyethylene. They also have improved electrical properties. The storage stability is greatly enhanced in formulations of silanecrosslinking adhesives and sealants.

Use of Silane OSi HIOSil VTMO as a co-monomer in polymer dispersions results in binders which exhibit much improved wet scrub resistance and higher abrasion resistance thanks to crosslinking and

improved adhesion to the substrate.

Applications

Silane OSi HIOSil VTMO is an essential ingredient in

many industries as below:

§ Moisture curing of polymers：

For the preparation of moisture-curing polymers 

§ Adhesion promotion & surface modification:  

As an efficient adhesion promoter for various mineral-filled polymers

§ As co-monomer for polymer dispersions:  

Improve adhesion strength in wet conditions and scrub resistance

§ As moisture scavenger:

Can react rapidly with water

§ Other applications:  

Can easily bond with OH-group. Hydroxyl containing polymers; it is activated by its proximity to silicon
