Description

[3-[(2-Aminoethyl)Amino]Propyl]Silanetriol is a bifunctional organosilane coupling agent featuring both silanol and primary/secondary amine groups. This unique structure enables it to act as a powerful adhesion promoter and surface modifier, creating strong covalent bonds between inorganic substrates and organic polymers. It is essential for manufacturers in the composites, coatings, and adhesive industries seeking to enhance material performance, durability, and interfacial strength.

Application

• Adhesion Promoter for glass, metal, and mineral-filled composites in automotive and aerospace parts.
• Surface Modifier for silica, glass fibers, and other inorganic fillers to improve dispersion and compatibility in polymer matrices like epoxies, nylons, and polyurethanes.
• Primer/Crosslinker in coatings, sealants, and adhesives to improve wet adhesion, corrosion resistance, and hydrolytic stability.
• Coupling Agent in mineral-filled rubber compounds and tire manufacturing to enhance mechanical properties.
• Sizing Agent for fiberglass and other reinforcing fibers to optimize the fiber-matrix interface.
• Intermediate for the synthesis of more complex silane derivatives and specialty polymers.

Quality Control

Our [3-[(2-Aminoethyl)Amino]Propyl]Silanetriol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay, identification, and impurity profiling, to ensure consistency and performance. A comprehensive Certificate of Analysis (COA) detailing purity and specifications is provided with every shipment to support your quality assurance protocols.

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). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed under an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and premature condensation/polymerization.
