Description

11-(o-Hydroxylamine)Undecyltriethoxysilane is a specialized bifunctional organosilane coupling agent that combines a reactive triethoxysilane group with a terminal hydroxylamine moiety. This unique structure makes it a critical component for creating covalent bonds between inorganic substrates and organic polymers, significantly enhancing adhesion, durability, and performance in composite materials. It is essential for manufacturers in the advanced materials, coatings, and adhesives industries seeking to improve the interfacial properties of their products.

Application

• Surface Modification Agent: For glass, silica, metals, and other inorganic fillers to improve compatibility and dispersion in polymer matrices like epoxies, polyurethanes, and polyamides.
• Adhesion Promoter: In high-performance primers, paints, and coatings for automotive, aerospace, and architectural applications where long-term bonding to metal or glass is required.
• Crosslinking Agent: For the synthesis of hybrid organic-inorganic materials (ORMOSILs) and sol-gel coatings with tailored mechanical and surface properties.
• Bioconjugation and Immobilization: As a linker molecule for attaching biomolecules, peptides, or catalysts to solid supports in diagnostic and biotechnological applications.
• Rubber and Composite Reinforcement: To enhance the bonding between silica fillers and rubber in tire manufacturing and high-performance elastomers.
• Fiber Treatment: For glass or carbon fibers in reinforced plastics (FRP) to increase interlaminar shear strength and environmental resistance.

Quality Control

Every batch of 11-(o-Hydroxylamine)Undecyltriethoxysilane is manufactured and tested under a strict quality management system. We ensure product consistency and purity through advanced analytical techniques including NMR, FT-IR, and HPLC. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and assay is provided with each 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 place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its hygroscopic and moisture-sensitive nature. Keep away from heat and incompatible materials. Allow the container to reach room temperature before opening to prevent moisture condensation.
