Silane USi-2301
Epoxy functional organosilane

Product Description

Chemical Name: 
γ-Glycidoxypropyltrimethoxysilane
Synonym:   Glymo;
Glycidyl 3-(trimethoxysilyl)propyl ether;
[3-(2,3-Epoxypropoxy)propyl]trimethoxysilane
CAS NO.:  2530-83-8
EINECS NO.:  219-784-2
 

 

Properties

The use of USi-2301 as a coupling agent
In mineral-filled plastics improves filler
dispersibility, reduces its sedimentation
tendency and greatly lowers the resin's
viscosity. In addition, it leads to higher filler
loading and a marked increase in water
(vapor) resistance, as well as resistance to
acids and bases. As a component of
adhesives and sealants,

USi-2301 improves both adhesion to the
substrate and mechanical properties such
as flexural strength, tensile strength and
modulus of elasticity.
