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.
