GC9003 Silane

H₂N(CH₂)₂NH(CH₂)₃Si(OCH₃)₂CH₃
Introduction
GC9003 is a colorless, strongly alkaline liquid with amine smell being very sensitive to hydrolysis.
GC9003 is a diamino-functional silane capable of providing good adhesion and superior elougation and flexibility at the polymer-substrate interface. It is used to promote adhesion between glass, mineral and metal surfaces-reinforcements, fillers and substrates-and resins that react with amino groups in systems such as PVC plastisol, polyurethane, or epoxy-based adhesives and sealant, or in phenolic and epoxy molding compounds. Its reduced alkoxy functionality might also be useful in waterborne systems such as latex coatings, adhesives and sealants, providing lower reactivity and therefore higher stability in the aqueous environment.
