sol-gel analysis, dynamic indentation, dynamic gas-abrasive determination and standard physical-mechanical assay methods were used. High value and quick rise of the exothermic curing reaction temperature result not only in decrease of the gelation time but lead to defective three-dimensional grid formation. Epikure F-205, CeTePox 1410H and Polyamine B hardeners provide maximum curing of the epoxy compositions that cause high physical-mechanical, viscoelastic properties and durability.
