Full Description

Vinyltris(2-methoxyethoxy)silane (CAS 1067-53-4) is a vinyl-functional silane bearing hydrolyzable 2-methoxyethoxy groups. It is documented as an adhesion/cohesion promoter and functions as a silane coupling agent linking inorganic fillers to polymer matrices.

Frequently Asked Questions

What is vinyltris(2-methoxyethoxy)silane used for?

Vinyltris(2-methoxyethoxy)silane (CAS 1067-53-4) is a vinyl-functional silane coupling agent that links inorganic fillers to polymer matrices. It is documented as an adhesion/cohesion promoter and crosslinker for filled polymer systems, including peroxide-cured and moisture-curable formulations.

What is the structure of vinyltris(2-methoxyethoxy)silane?

It has formula C11H24O6Si: a silicon center carrying one reactive vinyl group and three hydrolyzable 2-methoxyethoxy (methoxyethoxy) groups. The methoxyethoxy groups hydrolyze to bond inorganic surfaces while the vinyl group couples to the polymer.

How does it differ from vinyltrimethoxysilane or vinyltriethoxysilane?

All three are vinyl coupling-agent silanes; this one carries 2-methoxyethoxy leaving groups rather than methoxy (VTMS) or ethoxy (VTES). The bulkier methoxyethoxy groups change hydrolysis behavior and byproduct, which can suit specific filled-polymer and cable-compound systems.

What is the CAS number and identity of this silane?

The CAS number is 1067-53-4 and the formula is C11H24O6Si. It is classified under HS 2931.90 (other organo-inorganic compounds); identity is confirmed per lot on the Certificate of Analysis.

How is it packaged and priced in bulk?

This silane ships in drums and totes for polymer and cable-compound manufacturers. Packaging, MOQ, and pricing are volume-dependent; submit a bulk RFQ for current pricing and request the CoA and SDS.
