Description

Methyl-(N,n-Diethylaminomethyl)Diethoxysilane CAS NO 17961-68-1 is a specialized organosilicon compound featuring both alkoxysilane and tertiary amine functional groups. This unique bifunctional structure makes it a highly effective coupling agent and surface modifier, crucial for enhancing adhesion and compatibility between organic polymers and inorganic substrates. It is primarily sought by manufacturers in the advanced materials, coatings, and adhesive industries seeking to improve product performance and durability.

Application

• Adhesion Promoter: Used in epoxy, polyurethane, and acrylic-based coatings and adhesives to improve bonding to glass, metals, and mineral surfaces.
• Surface Modification: Imparts hydrophobic and organophilic properties to silica, glass fibers, and other fillers for better dispersion in polymer matrices.
• Crosslinking Agent: Functions as a co-curing agent in silicone sealants and RTV (Room Temperature Vulcanizing) rubbers.
• Fiberglass Sizing: A key component in sizing formulations for fiberglass reinforcements used in composite materials.
• Mineral Filler Treatment: Enhances the compatibility and performance of calcium carbonate, talc, and other fillers in plastics and elastomers.
• Catalyst and Intermediate: Serves as a precursor or catalyst in the synthesis of more complex organosilicon molecules and specialty polymers.
