Study of the effect of modification on the rheokinetics of epoxyamine composition curing using rheometry and differential scanning calorimetry

ITo obtain structural adhesives, a new method for modifying an epoxyamine matrix with an LPP brand adduct synthesized from oligoetherepoxide (Laproxide) in the presence of an excess of piperazine is considered. Curing kinetics of compositions has been studied by rheometry and DSC. Based on DSC data, equations that simulate curing at different stages of the process were proposed. The gelation times of the compositions have been established.
