Tetraglycidyl methylene dianiline epoxy

By reacting epichlorohydrin with aromatic diamines, it is possible to manufacture epoxy resins with higher functionality than DGEBA or DGEiBF resins. As shown in Fig. 5.9, the structure of tetraglycidyl methylene dianiline epoxy, the most important glycidyl amine, is characterized by four epoxy... 

Resin II contains tetraglycidyl methylene dianiline (TGMDA) as the principal epoxide with small amounts of a cresol novolac and DGEBA. DICY as curing agent is present in an amount such that the amine epoxy ratio is 0.25. Diuron is the accelerator. The supplier s recommended standard cure is the same as for SP250. However, in this system approximately 20 percent of the epoxide remains unreacted following the cure cycle (1 ). Selected resin plates were subjected to additional cure at 170°C and 220°C. The samples post cured at 220 C for forty minutes showed no residual epoxide absorbance in the IR spectrum. 

Epoxy resins containing N,N -tetraglycidyl methylene dianiline (TGMDA) are widely used in the manufacture of fiber-reinforced structural composites for aerospace applications.
