HENGDA-M8252 - N-(2-Aminoethyl)-3-aminopropylmethyldimethoxysilane

HD-602
HENGDA-M8252

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.

Applications

1. N-(2-Aminoethyl)-3-Aminopropylmethyldimethoxysilane is used as an additive for cold-curing phenolic and furan foundry resins to improve the flexural strength of the sand-resin composites while maintaining the shelf life of the resin over long periods.

2. It is used as the raw material in the synthesis of amino silicone fluids or amino fuctional siicones.

3. It can be added to 1 part- and 2-part polysulfide/silicone-crosslinked sealants, provide better adhesion to a variety of substrates, including glass, aluminum and steel.

4. It is used as an additive to phenolic resin binders for mineral fiber insulating materials.

5. N-(2-Aminoethyl)-3-Aminopropylmethyldimethoxysilane is used in the surface modification of silicon-containing materials such as glass beads, silica, talc, mica, clay.
