1 of 96 products in this brand
Silquest™ silane Y-9669 combines phenyl and amino functionality in the same molecule.It is an extremely effective adhesion promoter for many filled and reinforced resin systems. Silquest™ silane Y-9669 is a versatile adhesion promoter, particularly for resin systems that will react with a secondary amino group, such as isocyanates, acrylates, epoxies, phenolics and RTV silicones. This silane is especially useful when the resulting material must withstand higher temperatures; e.g., in phenolic resin/fiberglass composites.

Functions: Adhesion Promoter, Coupling Agent, Water Repellent

Chemical Family: Amines, Silanes
