N-(3-(Trimethoxysilyl)propyl)butylamine

Amino functional silane coupling agent. Secondary amine formed by reacting an aminopropyltrimethoxysilane with a butyl group, giving a bulkier, less basic amine than the primary aminopropyl silanes — this reduces premature reaction with acidic fillers or resins while still promoting adhesion. Releases methanol on hydrolysis.
