HENGDA-E8132 - 3-Aminopropylmethyldiethoxysilane

HD-520
HENGDA-E8132

3-Aminopropylmethyldiethoxysilane is an organosilane coupling agent that contains both an amino (-NH₂) group and an ethoxy (-OEt) group attached to a propyl chain (-CH₂CH₂CH₂NH₂).
Here are the key aspects of 3-aminopropylmethyldiethoxysilane:
Aminopropyl group (-CH₂CH₂CH₂NH₂): Provides primary amine functionality, making it reactive towards various substrates.
Methyldiethoxysilane group (-Si(OEt)₂CH₃): This group is hydrolysable, allowing it to bond strongly to inorganic surfaces.
