Product Description
Abstract
Vinyltri(2-methoxyethox , y)silane (CAS No. 1067-53-4), silane coupling agent SCA-
V71C, is a bifunctional organosilane possessing a reactive vinyl group and a
hydrolyzable inorganic 2-methoxy-ethoxy-silyl group. The dual nature of its
reactivity allows SCA-V71C to bind chemically to both inorganic materials (e.
G. Glass, metals, fillers) and organic polymers (e. G. Thermosets,
thermoplastics, elastomers), thus functioning as a crosslinking agent, adhesion
promoter and/or surface modifier.
SCA-V71C is a colorless, low-viscosity liquid with a typical aromatic odor.

Application
Vinyltri(2-methoxyeth , oxy)silane (CAS No. 1067-53-4), silane coupling agent SCA-
V71C, is an important additive for many applications. Examples are:
1. Emulsion polymerization: As a monomeric vinyl functional silane in vinyl,
vinyl acrylic and acrylic resin, this vinyl silane can be added as monomers
during emulsion during polymerization to form silane modified latexes. The
silane in such latexes functions as crosslinkers, forming very stable Si-O-Si
chain.
2. Silane crosslink polymers: This vinyl silane can also grafted to select
unsaturated polymers such as PE, PET and Styrene-Butadiene co-polymer, via
moisture cure mechanism. These vinyl silane crosslinked polymers represent good
resistant to high temperature and excellent mechanic strength.
3. Adhesives, sealants and hot melt: Excellent adhesion to a wide range of
inorganic substrates such as metal, glass and concrete, the suitable resins
include acrylic, vinyl and vinyl acrylic.
4. Polymer dispersions: Polymer dispersions (e. G. Styrene acrylics), modified
with SCA-V71C show improved adhesion strength in wet conditions and wet scrub
resistance.
