TTA520: 4,4′-Methylenebis(N,N-diglycidylaniline) Cas 28768-32-3


TTA520 (4,4′ diaminodiphenylmethane tetraglycidylamine) is a multifunctional high temperature resistant special epoxy resin. Its structure is characterized by the non-glycidyl ether structure with polyphenyl ring and polycyclic oxygen group in the molecule. TTA520 can be cured with anhydrides or amines. Its cured product has the characteristics of high crosslinking density, strong structural rigidity, low defects and low water absorption, as well as excellent heat resistance, weather resistance, chemical resistance, corrosion resistance and good mechanical properties.


Application Possibility

As the matrix resin of fiber composites, TTA520 has long pot life, excellent fiber impregnation, and good processability.


TTA520 is applicable for filament winding, pultrusion molding, RTM molding, and other molding processes.


In addition, TTA520 has excellent corrosion resistance, chemical resistance, and weather resistance, high bonding strength, and good mechanical properties.


It can be widely used in composite resin, high-temperature resistant adhesive, automobile lightweight, communication cable, military aerospace, rail transit, sports equipment, coating corrosion resistance, and other fields.
