Silquest™ Y-9669

It is the n-phenyl-gamma-aminopropyltrimethoxysilane. Acts as adhesion promoter. Silquest Y-9669 combines phenyl and amino functionality in the same molecule. Evaluation is recommended for such polymers as urethanes, epoxies, acrylates and phenolics that must adhere to inorganic substrates; e.g. glass, metals, fiberglass and particulate fillers. Has phenyl group for good resin wet-out, methoxy silane ester for fast hydrolysis time, aromatic amino group for increased stability of resin/silane bond at elevated temperature. It is an extremely effective adhesion promoter for many filled and reinforced resin systems. Applications include glass fiber sizes, finishes, laminates and foundry sand binders.
