“…Since the early 1950s, epoxide oligomers have been actively used in the aerospace, mechanical engineer ing, and civil industries (construction, radiotechnics, shipbuilding) as glues, coatings, and polymeric com posite materials [1][2][3][4][5][6][7][8][9]. However, to obtain materials with optimal operational properties based on epoxy oligomers, it is necessary to choose the right composi tion of a curing system and the right curing regime.…”

To decrease the curing temperature of epoxy compositions at the use of dicyandiamide (DCDA) as a latent hardener, a curing catalyst system including, in addition to DCDA, asymmetric urea has been stud ied. The dependencies of parameters of chemical transformations in catalyzed epoxy compositions, such as thermal effects and conversion, on the composition of the complex curing catalyst system have been estab lished by the DSC and isothermal calorimetry techniques. It has been shown that the chosen optimal com position of the catalyst system allows curing the epoxy compositions in a two stage regime at lower tempera tures than in the case of the use of DCDA.
