Product introduction

YAC-A2523 is a bifunctional silane with reactive amino groups and hydrolyzable inorganic ethoxysilyl groups. Due to the nature of its amino group, this substance reacts as a strong base.

The silane hydrolyzes autocatalytically in the presence of moisture (ethanol 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 bind to both inorganic materials and organic polymers to function as a molecular bridge between organic and inorganic substrates.

YAC-A2523 amino silane is the equivalent of Dow's Z-6021, Wacker's GF94, ShinEtsu's KBE-603. It is a clear, colorless, strongly alkaline liquid.


YAC-A2523 silane coupling agent is mainly used for coupling organ-polymers and inorganic fillers, combining both of them as a body and improving the characters of mechanic, electric, water resistance and antiaging of these composites.

Packing and Storage

YAC-A2523 is supplied in 190Kg steel drum or 950Kg IBC container.

In the unopened original container YAC-A2523 has a shelf life of one year in a dry and cool place.
