Description

11-(o-Hydroxylamine)Undecyltrimethoxysilane is a specialized bifunctional organosilane coupling agent featuring a reactive hydroxylamine group and a hydrolyzable trimethoxysilane group. This unique structure makes it a critical component for creating covalent bonds between inorganic substrates and organic polymers, significantly enhancing adhesion, durability, and performance. It is essential for R&D scientists and production engineers in the advanced materials, specialty coatings, and composites industries seeking to develop high-performance, surface-modified products.

Application

• Surface Priming Agent: Used to functionalize glass, metal, and mineral surfaces to improve the adhesion of paints, adhesives, and polymer coatings.
• Crosslinking Agent: Serves as a reactive intermediate in the synthesis of hybrid organic-inorganic polymers and networks for high-strength composites.
• Corrosion-Resistant Coatings: Incorporated into silane-based pretreatment systems for metals like aluminum and steel to enhance corrosion protection.
• Filler Modification: Treats silica, glass fibers, and other mineral fillers to improve their compatibility and dispersion within rubber and plastic matrices.
• Bioconjugation & Immobilization: Utilized in life sciences for attaching biomolecules (e.g., proteins, DNA) to solid supports like glass slides or nanoparticles via its hydroxylamine group.
• Adhesive Formulation: Enhances the bond strength and environmental resistance of structural and specialty adhesives, particularly on difficult-to-bond substrates.

Quality Control

Every batch of 11-(o-Hydroxylamine)Undecyltrimethoxysilane is manufactured and tested under a strict quality management system to ensure consistent purity and performance. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and key parameters is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under a dry inert atmosphere (e.g., nitrogen) for long-term storage to prevent hydrolysis and degradation.
