Grade: CG-ND22
Diethyl amino methyl triethoxy silane
CG-ND22 (Diethyl amino methyl triethoxy silane) is one of the Alpha silane series products. Its organic reactive functional group is positioned closer to the central silicon atom, and the shorter alkyl chain segment makes the ethoxy groups attached to the silicon atom more reactive. Its hydrolysis reaction rate is much faster than that of conventional γ-type aminosilanes, resulting in faster curing of the products.

Packaging and Storage
This product can be packaged in 25 kg plastic drums, 200 kg plastic drums, or steel drums. Other package sizes are available upon request. Store in a cool, well-ventilated, dry place in tightly sealed containers, protected from light. Keep away from moisture and sources of ignition. Ensure the lid is tightly sealed and effectively isolates the product from air; moisture in the air can react quickly, thereby leading to hydrolysis and polymerization. Shelf life in the original unopened packaging is one year. This product is irritating to skin and eyes. If it contacts skin, wash with soap. If it contacts eyes, rinse immediately with plenty of water.
Application
CG-ND22 is used as a surface treatment agent for bonding silicone rubber to metal to improve the adhesion between silicone rubber and metal.
CG-ND22 is used as a curing agent for room-temperature vulcanizing (RTV) silicone rubber, as well as a curing agent and tackifier for epoxy resin. It enables RTV silicone rubber to bond to glass, ceramics, cement, various plastics, and most metals, with bonding strength greater than that of the silicone rubber itself, while maintaining compatibility with silicone rubber's high-temperature resistance, low-temperature resistance, and electrical properties.
