Description

N,N'-Bis[2-[[3-(Trimethoxysilyl)Propyl]Amino]Ethyl]Ethylenediamine Dihydrochloride is a high-purity, multi-functional organosilane coupling agent with a polyamine backbone. This compound is engineered to provide superior adhesion and compatibility between inorganic materials and organic polymers, making it a critical performance additive. It is primarily utilized in advanced material science applications where enhanced durability and interfacial bonding are required. The product is supplied as a dihydrochloride salt to improve its stability and handling characteristics.

Application

• Surface Modification Agent for glass, silica, and metal oxides to improve polymer adhesion.
• Crosslinking and Coupling Agent in epoxy, polyurethane, and silicone resin formulations.
• Adhesion Promoter in high-performance coatings, paints, and sealants for automotive and aerospace industries.
• Filler Treatment for minerals and nanoparticles (e.g., silica, clay) in composite materials to enhance dispersion and mechanical properties.
• Intermediate for the synthesis of more complex silane-based specialty chemicals and dendrimers.
• Fiber Sizing for glass and carbon fibers to strengthen the fiber-matrix interface in reinforced plastics.

Quality Control

Our production of N,N'-Bis[2-[[3-(Trimethoxysilyl)Propyl]Amino]Ethyl]Ethylenediamine Dihydrochloride adheres to stringent quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, impurity profiling, and functional group verification. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under dry conditions to prevent degradation. Keep away from incompatible materials such as strong acids and bases.
