Molecular Structure

Structure Analysis

With a plurality of epoxy groups and benzene ring in structure, the curing process can form a relatively high crosslinking and aromatic density, which brings the curing product good heat resistance and thermal stability, excellent high-temperature long-term strength maintain performance, low cure shrinkage, chemical resistance, resistance to radiation and heat distortion temperature. Different from conventional high-temperature with high softening point resin type such as phenol epoxy resin, polyimide resin, polysulfone, 4,4′-METHYLENEBIS(N,N-DIGLYCIDYLANILINE)-Epoxy Resin(MY720) CAS 28768-32-3 has low viscosity, whose cured product has high mechanical strength and electrical insulation properties. These features above enable it of conventional processing technology and solvent-free operation, which can be used in high class heat-resistant carbon fiber, aramid fiber and glass fiber composite materials, whose reaction activity is higher than conventional epoxy resins, shortening curing time and improving production efficiency.

Performance Indicator Reference Of Resin Casting Body

A variety of curing agents are applicable for 4,4′-METHYLENEBIS(N,N-DIGLYCIDYLANILINE)-Epoxy Resin(MY720) CAS 28768-32-3, typically methyl tetrahydrophthalic anhydride, methyl hexahydrophthalic anhydride, hexahydrophthalic anhydride, methylnadic anhydride and aromatic amine curing agents such as diaminodiphenyl sulfone (DDS) and diamino diphenyl methane (DDM). Usage amount and temperature control should be strictly paid attention to. Exothermic reaction should be especially concerned when using the accelerator to prevent implosion.
