Product Description

Chemical Name:  

γ-Aminopropyltrimethoxysilane

Synonym:  

3-(Trimethoxysilyl)-1-propanamine

CAS NO.:  13822-56-5

EINECS NO.:  237-511-5

Properties

In addition to its application as an adhesion

Promoter in formulations and primers, Silane OSi HIOSil AMMO functions as a surface modifier in fillers and pigments, where it improves the dispersibility of the filler and the mechanical properties - such as flexural strength, tensile strength and modulus –of the composites. The silane also reduces the filler's sedimentation tendency in the uncured polymer.

Silane OSi HIOSil AMMO also greatly increases water

(vapor) and corrosion resistance.
