N-(2-Aminoethyl)-3-aminopropylmethyldimethoxysilane is a specific organosilane coupling agent that contains both amino (-NH₂) and alkoxysilane (-Si(OR)₂CH₃) groups in its structure.
The molecule consists of:
Aminoethyl group (-CH₂CH₂NH₂): Provides primary amine functionality, which is reactive towards various substrates.
Aminopropyl group (-CH₂CH₂CH₂NH₂): Adds additional amine functionality, enhancing its reactivity.
Methyldimethoxysilane group (-Si(OCH₃)₂CH₃): This group is hydrolysable, allowing it to bond strongly to inorganic surfaces.
