Description

Bis[N,N'-(Triethoxysilylpropyl)Aminocarbonyl]Polyethylene Oxide (10-15 Eo) is a specialized organosilane coupling agent with a unique polyethylene oxide (PEO) spacer. This compound is engineered to provide superior adhesion promotion and compatibility between inorganic substrates and organic polymer matrices. It is essential for formulators and material scientists seeking to enhance the mechanical properties, durability, and performance of composite materials. Its bifunctional structure makes it a critical component in advanced coatings, adhesives, and sealants.

Application

• Adhesion Promoter in Coatings: Enhances the bonding of paints, primers, and functional coatings to glass, metal, and mineral surfaces, improving scratch and corrosion resistance.
• Composite Material Modifier: Used as a coupling agent in fiberglass, mineral-filled plastics, and rubber composites to improve interfacial strength and dispersion.
• Sealant and Adhesive Formulation: Improves the adhesion and flexibility of high-performance silicone, polyurethane, and epoxy-based sealants and adhesives.
• Surface Treatment for Nanoparticles: Functionalizes silica, alumina, and other nanoparticles to improve their compatibility and prevent agglomeration in polymer hosts.
• Textile and Fiber Finishing: Imparts durable hydrophilicity, softness, and anti-static properties to synthetic fibers and fabrics.
• Biomaterial and Medical Device Coating: Used to create biocompatible, non-fouling surfaces on medical implants and devices due to its PEO segment.

Quality Control

Our production of Bis[N,N'-(Triethoxysilylpropyl)Aminocarbonyl]Polyethylene Oxide adheres to strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay by NMR or titration, determination of ethoxy content, and verification of moisture levels to ensure consistency and performance. Certificates of Analysis (COA) documenting purity, identity, and key physical parameters are provided with every shipment. We support compliance with relevant global regulatory frameworks, including REACH.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis and maintain product integrity. Keep away from heat and incompatible materials.
