Investigation of the effect of polyesteramides based on secondary PET on the curing process and properties of epoxy filling compositions

Abstract

Filling compositions based on epoxy-diane resin have been developed, the curing process using polyesteramides has been investigated, and the activation energies of the curing reaction have been calculated. The effect of increasing the amount of PET on the thermal characteristics and physico-mechanical properties of filling compositions is shown. The test results show that the filling compositions obtained using the developed polyesteramides are superior in properties to compositions based on industrial amine hardeners.
