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.

3-Aminopropylmethyldiethoxysilane is mainly used to increase the bonding ability of organic materials to inorganic materials, suitable for most organic and inorganic materials.
1. It is used as the raw material for amino silicone fluids and various silicone softening agents.
2. It is used in silicone-crosslinked and polysulfide sealant, to improve the adhesion to substrates (cement, copper, glass, etc.).
