Description

3-Aminopropyltris(Methoxyethoxyethoxy)Silane is a specialized organosilicon coupling agent featuring a primary amine functional group and a hydrophilic tri(ethylene glycol) methyl ether chain. This unique structure makes it a critical component for enhancing adhesion and compatibility between inorganic substrates and organic polymers. It is essential for formulators and manufacturers in advanced materials sectors who require durable, high-performance surface modifications. The compound is supplied under strict quality control to ensure batch-to-batch consistency for industrial applications.

Application

• As a silane coupling agent for surface treatment of glass, metals, and minerals to improve adhesion with epoxy, polyurethane, and acrylic resins.
• Key ingredient in formulating water-based primers and adhesion promoters for coatings, inks, and adhesives.
• Surface modification of nanoparticles (e.g., silica, titania) to enhance dispersion and stability in polymer matrices and composite materials.
• Functionalization agent in the manufacture of biomedical and diagnostic materials, leveraging its amine group for further conjugation.
• Improving the mechanical properties and moisture resistance of fiber-reinforced composites and mineral-filled plastics.
• Used in electronic encapsulants and potting compounds to promote adhesion and reduce interfacial stress.

Quality Control

Our 3-Aminopropyltris(Methoxyethoxyethoxy)Silane is manufactured under a cGMP-compliant quality management system. Each batch undergoes rigorous analytical testing, including NMR, FT-IR, and HPLC, to verify identity, purity, and functional group integrity. We provide full traceability and comprehensive Certificates of Analysis (COA) upon request, ensuring the material meets the stringent requirements of research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 15-25°C. This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
