Description

[3-[(2-Aminoethyl)Amino]Propyl]Silanetriol, Monohydrochloride is a bifunctional organosilane coupling agent featuring both a hydrolyzable silanetriol group and a primary amine hydrochloride moiety. This unique structure makes it a critical component for creating strong, durable bonds between inorganic substrates and organic polymers or coatings. It is essential for formulators and manufacturers seeking to enhance adhesion, improve mechanical properties, and ensure long-term stability in composite materials. Key industries that rely on this specialty silane include advanced composites, adhesives and sealants, and surface treatment technologies.

Application

• Glass Fiber & Mineral Filler Treatment: As a coupling agent to improve the interfacial adhesion between glass fibers or mineral fillers (e.g., silica, clay) and polymer matrices in reinforced plastics and composites.
• Adhesive & Sealant Formulations: To enhance the bond strength and durability of epoxy, polyurethane, and acrylic-based adhesives and sealants, particularly on challenging substrates like metals, glass, and ceramics.
• Surface Primers & Coatings: Used in primers and functional coatings to promote adhesion and provide corrosion resistance on metal surfaces such as aluminum and steel.
• Rubber & Tire Manufacturing: As a key ingredient in silica-reinforced rubber compounds, improving filler dispersion, reducing rolling resistance, and enhancing wear resistance in tire treads.
• Electronics Encapsulation: To improve the adhesion and moisture resistance of epoxy molding compounds used to encapsulate sensitive electronic components.
• Dental & Biomedical Composites: Employed as a coupling agent in dental restorative materials and bone cements to strengthen the filler-resin interface.
