Product Description

Chemical Name:

3-Methacryloxypropyltrimethoxysilane

Synonym:  

3-Trimethoxysilyl-propyl-methacrylate;        [3-(Methacryloyloxy)propyl]trimethoxysilane;

CAS NO.:   2530-85-0

EINECS NO.:   219-785-8

Properties

Silane OSi HIOSil MEMO, as a coupling agent in glass fiber-reinforced or filler-modified plastics improves filler dispersibility while reducing the filler's sedimentation tendency.

It is also a major reduction in the melt viscosity of casting resins, as well as a marked improvement in the mechanical properties of glass-fiber-reinforced or mineral-filled plastics. In addition, it leads to a sizable increase in moisture resistance and greater resistance to acids and bases.

Used as a co-monomer in polymers, Silane OSi HIOSil MEMO produces binders that exhibit much improved wet scrub, abrasion and scratch resistance. As a component of free-radical curable adhesives and sealants.
