Description of m-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline
m-(2,3-Epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline (CAS: 71604-74-5), also known as Triglycidyl-m-aminophenol (TGMAP) or AFG-90M, is a trifunctional epoxy resin. This highly reactive epoxy monomer features three epoxy groups attached to an aromatic amine backbone, enabling rapid curing with amines, anhydrides, or other hardeners.
Application of m-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline
High-Performance Composite Matrix Resin. Serves as a trifunctional epoxy resin for advanced carbon fiber composites, providing excellent mechanical strength, high Tg (>200°C), and superior toughness.
Aerospace Structural Materials. Used in prepregs and RTM formulations for aircraft components, offering low viscosity for complex molding and outstanding thermal/chemical resistance.
Automotive and Lightweight Parts. Enables high-performance epoxy systems for structural adhesives and lightweight composites in electric vehicles and high-end automotive applications.
Electronics and Encapsulation. Applied in potting compounds and encapsulants for electronic devices, delivering high dielectric strength, low moisture absorption, and reliability under harsh conditions.
Adhesives and Coatings. Functions as a reactive modifier in structural adhesives and high-temperature coatings, enhancing adhesion, flexibility, and durability.
Storage of m-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline
It should be kept in a tightly sealed original container in a cool, dry, well-ventilated area away from direct sunlight, heat, and moisture. Recommended storage temperature: 5–25°C (preferably 2–8°C for longer stability). Keep away from strong acids, bases, amines, and oxidizing agents to prevent premature curing or polymerization. The product is moisture-sensitive and can react with water or humidity. Use an inert atmosphere (nitrogen) if possible.
