Title: 2,5 dimethyl 2,5 hexane diamine: a promising new curing agent for epoxy resins

Journal Article · · SAMPE Q.; (United States)
OSTI ID:5562864

A new curing agent for epoxy resins that has both interesting and useful properties was found. The compound, 2,5 dimethyl 2,5 hexane diamine (DMHDA) is a sterically hindered primary aliphatic amine that, as a curing agent for DGEBA epoxy resins, has the following desirable characteristics: at room temperature it forms a stable B-stage resin; it is a good wet-filament winding resin having a low viscosity (0.5 Pa.s) and a long gel time (21 h for a 30-g mass); the cured resin properties are good, for example, the tensile strength is 86 MPa (12,500 psi), and the glass transition temperature is greater than 140/sup 0/C when cured at 130/sup 0/C.
