Description

Bis[3-(Triethoxysilyl)Propyl]Amine CAS NO 13497-18-2 is a bifunctional organosilane coupling agent featuring both amine and triethoxysilyl groups. This dual functionality makes it a critical component for enhancing adhesion, compatibility, and cross-linking between inorganic materials and organic polymers. It is primarily sought after by manufacturers in the advanced materials, coatings, and sealants industries for its ability to improve mechanical properties and chemical resistance.

Application

• As a coupling agent and adhesion promoter in epoxy, polyurethane, and acrylic-based coatings and adhesives.
• For the surface modification of inorganic fillers (e.g., silica, glass fibers, minerals) to improve dispersion and bonding in polymer composites.
• As a key intermediate in the synthesis of specialty silicones and silane-modified polymers (SMP).
• In the formulation of moisture-curable sealants and primers for construction and automotive applications.
• For corrosion inhibition in metal surface treatment formulations.
• As a cross-linking agent in sol-gel processes for creating hybrid organic-inorganic materials.
