Vinyl tris(2-methoxyethoxy) silane
Silane coupling agent Censil 172 can dissolve in methanol, ethanol, toluene, xylene and acetone. When stir it fully, it can dissolve in water and the water solubility can reach 5%w/w.
Silane VTMOEO Crosile172 Vinyltris(2-methoxyethoxy)
ECOPOWER Crosile®172 is a vinyl-functional coupling agent that promotes adhesion among unsaturated, polyester-type resins
or crosslinked polyethylene resins or elastomers and inorganic substrates, including fiber glass, silica, silicates and many metal oxides. When used as coupling agent, it reduces the sensitivity of the products’ mechanical and electrical properties to heat and/or moisture.

Censil 172 is an efficient adhesion promoter for various mineral-filled polymers, improving mechanical and electrical properties
especially after exposure to moisture.
Censil 172 is 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.
Censil 172 improve the compatibility of fillers with polymers, leading to a better dispersibility, reduced melt viscosity and easier
processing of filled plastics.
VTMOEO is used to pretreat of glass, metals, or ceramic surfaces, improve the adhesion of coatings on these surfaces and corrosion resistance.
