Product Description

Chemical Name: 

Vinyl-tri(β-methoxyethoxy)silane

Synonym:  

Tris(2-methoxyethoxy)vinylsilane

CAS NO.:  1067-53-4

EINECS NO.:  213-934-0

Properties

Silane USi-412 acts as an adhesion

promoter for various mineral-filled

polymers improving their mechanical and

electrical properties, especially after

exposure to moisture. Once bonded to an

inorganic filler.

Silane USi-412 hydrophobises the filler

surface. This effect improves the

compatibility of fillers with the polymer

matrix, leading to a better dispersibility,

reduced melt viscosity and easier

processing of filled plastics.

Polymer dispersion, modified with silane

USi-412 show improved adhesion strength

in wet conditions and wet scrub resistance.

Applications

Silane USi-412 is an vital additive  in

many industries such as:

§   Enhances electric property and

mechanical strength: 

As the surface treating agent for the

pottery clay and siliceous inorganic filler

§   Enhances mechanical strength of

composite materials:

It can reduce the water absorbability,

electric property and mechanical

strength of the cross-linked polyester

mould pressing materials.

§   In the glass fiber application: 

It enhances the binding power of resins
