Abstract

The mechanical properties of copper coatings based on epoxy resins ED-20, E-40, KER 828, Etal 245 and experimental hardeners: terpenoid maleic adducts (TDMA) and rosin-terpene maleic adducts (CTMA) were studied. A comparative analysis of the hardness and impact strength of coatings on copper substrates cured with TDMA and KTMA and standard hardeners: polyethylene polyamine (PEPA), triethylenetetramine (TETA) was performed. The influence of the plasticizer on the physical and mechanical properties of coatings has been established. The activation energy of thermo-oxidative destruction of coatings cured with different hardeners is estimated. For the first time, calculations of the durability of coatings were performed using the developed express method.
