【Abstract】 An eutectic aromatic amine curing agent for epoxy has been obtained by physically eutectic mix of p,p′ diamino diphenylmethane (DDM) and dimethyl mercapto methyl benzenedioomamine (DADMT). Its effects on the mechanical properties, gelation behaviour and thermal stabilities of resin system were studied. The experimental results show that the use of this eutectic mixture can prolong the pot life of resin system and improve its mechanical properties.更多还原
