Description

n-[3-[Tris(Decyloxy)Silyl]Propyl]Ethylenediamine is a specialized organosilicon compound featuring a unique molecular architecture that combines a silyl ether core with a diamine-terminated propyl linker. This structure is engineered to provide dual functionality, acting as a coupling agent and surface modifier to enhance adhesion and compatibility between organic polymers and inorganic substrates. It is a critical material for formulators and manufacturers in advanced material science seeking to improve the performance and durability of composite systems.

Application

• Coupling Agent for Composites: Enhances the interfacial bonding between inorganic fillers (like silica, glass fibers, or minerals) and organic polymer matrices (epoxy, polyurethane, nylon), improving mechanical strength and moisture resistance.
• Surface Modification of Nanoparticles: Used to functionalize the surface of metal oxides or other nanoparticles to prevent agglomeration and improve dispersion in various media for coatings, inks, or electronic materials.
• Adhesion Promoter in Coatings & Sealants: Incorporated into primers, paints, and sealant formulations to promote adhesion on difficult substrates like glass, metals, and treated plastics.
• Fabric Treatment: Imparts durable water repellency (DWR) and stain resistance to textiles and non-woven materials.
• Rubber & Tire Industry: Improves the reinforcement of silica-filled rubber compounds, leading to better rolling resistance, wet grip, and abrasion resistance in tire manufacturing.
• Resin & Plastic Additive: Serves as an internal modifier to increase the toughness and thermal stability of engineering plastics and thermosetting resins.

Quality Control

Our production of n-[3-[Tris(Decyloxy)Silyl]Propyl]Ethylenediamine adheres to a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Key parameters monitored include assay (purity), moisture content, and functional group integrity. A comprehensive Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your specifications and industry standards.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from strong oxidizing agents.
