The unmodified GY epoxy resin (Vantico AG) was crosslinked by the aliphatic and cycloaliphatic EH polyamine adduct (Solutia-Vianova) in the different stoichiometric ratio. The optimal time of total crosslinking was determined by indirect measuring of the film hardness. The degree of the epoxy resin crosslinking and the quantity of unreacted epoxy groups have been monitored by the spectroscopic FT-IR method. The content and intensity changes of hydroxy group were correlated to the extent of epoxy reaction and crosslinking degree. By the parameters correlation and a period of resins application, optimal resin/hardeners stoichiometric ratio was defined. It was prerequisite for three-component epoxy system forming which is comparatively more elastic, adhesion and waterproof.
