Product introduction

YAC-A4713 is an organofunctional silane possessing three reactive amino groups and a hydrolyzable trimethoxysilyl group. Due to the nature of its amino group, this substance reacts as a strong base.

The silane hydrolyzes autocatalytically in the presence of moisture (methanol is released) to form silanols, which can then react with themselves to produce siloxanes or can bind to inorganic substrates. As a bifunctional organosilane, it can also interact with numerous organic polymers and thus function as a molecular bridge (adhesion promoter, surface modifier) between organic and inorganic substrates.

YAC-A4713 amino silane is a clear, light to dark yellow liquid with a slight amine-like odor. It is soluble in alcohols, ketones, esters and aliphatic and aromatic hydrocarbon solvents. It is the equivalent of Momentive's A-1130, Dow's AY43-009, Evonik's Dynasylan TRIAMO silane.


YAC-A4713 can be used as an adhesion promoter in sealants, adhesives and coatings, specifically suited for plastisol sealants.

YAC-A4713 can be used as a silane surface modifier for fillers.

YAC-A4713can be used in the production of silyl-modified polymers which serve as binders in adhesives and sealants.

Packing and Storage

YAC-A4713 is supplied in 200Kg steel drum or 1000Kg IBC container.

In the unopened original container YAC-A4713 has a shelf life of one year in a dry and cool place.
