Description

N,N'-Bis[3-(Dimethoxymethylsilyl)-2-Methylpropyl]Ethylenediamine is a specialized organosilicon compound featuring a unique bifunctional structure that combines a diamine core with alkoxysilyl groups. This molecular architecture makes it a highly effective coupling agent and adhesion promoter, crucial for creating durable bonds between organic polymers and inorganic substrates. It is primarily sought after by manufacturers in the advanced composites, sealants, adhesives, and coatings industries who require enhanced material performance and long-term stability in demanding environments.

Application

• As a silane coupling agent to improve the adhesion of epoxy, polyurethane, and acrylic resins to glass, metals, and mineral fillers.
• As a key intermediate in the synthesis of specialty silicone polymers and modified resins for high-performance coatings and sealants.
• For surface treatment of glass fibers and minerals (e.g., silica, clay) to enhance compatibility and dispersion in plastic and rubber composites.
• In the formulation of primers and adhesion promoters for automotive, aerospace, and construction applications.
• As a crosslinking agent or chain extender in the production of polyurea and polyamide systems.
• For modifying filler surfaces in tire and rubber manufacturing to reduce hysteresis and improve mechanical properties.

Quality Control

Our production of N,N'-Bis[3-(Dimethoxymethylsilyl)-2-Methylpropyl]Ethylenediamine adheres to stringent quality management protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed using advanced techniques including GC, NMR, and titration to verify critical parameters such as assay, amine value, and silane content. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after initial use to prevent moisture absorption, which can affect product performance. Keep away from strong acids and bases.
