Description

n-(6-Aminohexyl)Aminopropyltrimethoxysilane is a bifunctional organosilane coupling agent featuring both primary amino and hydrolyzable methoxysilyl groups. This dual functionality is critical for creating strong, durable bonds between inorganic materials and organic polymers. It is essential for manufacturers seeking to enhance the mechanical properties, adhesion, and durability of composite materials. Key industries that rely on this silane include advanced composites, coatings, adhesives, and sealants.

Application

• As a coupling agent in glass fiber-reinforced plastics (GRP) and mineral-filled composites to improve interfacial adhesion and mechanical strength.
• Surface modification of silica, alumina, and other inorganic fillers to improve their dispersion and compatibility in polymer matrices like epoxy, nylon, and polyurethane.
• A key intermediate in the synthesis of specialized silicone polymers and resins with tailored properties.
• An adhesion promoter in primers, paints, and coatings for metals, glass, and plastics to enhance corrosion resistance and durability.
• Used in the formulation of high-performance sealants and adhesives to improve bonding to difficult substrates.
• Potential applications in the modification of surfaces for biomedical or chromatographic purposes due to its amino functionality.

Quality Control

Our n-(6-Aminohexyl)Aminopropyltrimethoxysilane is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay by titration or GC, to ensure consistent purity and performance. Certificates of Analysis (COA) detailing specific batch results are provided and available upon request 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 a dry inert atmosphere (e.g., nitrogen) to prevent hydrolysis and maintain product integrity.
