Description

n-(6-Aminohexyl)Aminomethyltrimethoxysilane is a bifunctional organosilane coupling agent featuring both primary amine and hydrolyzable methoxysilyl groups. This dual functionality is critical for creating strong, durable bonds between inorganic materials and organic polymers or resins. It is an essential raw material for formulators and manufacturers seeking to enhance composite material performance. Key industries that rely on this silane include advanced composites, adhesives, sealants, and surface treatment technologies.

Application

• As a coupling agent in glass fiber-reinforced plastics (GRP) and mineral-filled composites to improve mechanical strength and moisture resistance.
• Surface modification of silica, glass, and metal oxides to introduce reactive amine groups for further functionalization.
• A key adhesion promoter in epoxy, polyurethane, and phenolic resin-based adhesives and sealants.
• Used in the formulation of primers and coatings to enhance adhesion to difficult substrates like metals and glass.
• As a crosslinking agent or chain extender in specialty polymer synthesis.
• Surface treatment for nanoparticles to improve dispersion and compatibility in polymer matrices.
• In the manufacture of moisture-curable resins and silane-modified polymers (SMP).

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, 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 degradation upon contact with atmospheric moisture.
