AB  - 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.

AB  - The use of fast FT-IR spectroscopy as a sensitive method to estimate a change of the crosslinking kinetics of epoxy resin with polyamine adducts is described in this study. A new epoxy formulation based on the use of polyamine adducts as the hardeners was analyzed. Crosslinking reactions of the different stoichiometric mixtures of the unmodified GY250 epoxy resin with the aliphatic EH606 and the cycloaliphatic EH637 polyamine adducts were studied using mid FT-IR spectroscopic techniques. As the crosslinking proceeded, the primary amine groups in polyamine adduct are converted to secondary and the tertiary amines. The decrease in the IR band intensity of epoxy groups at about 915 cm(-1), as well as at about 3,056 cm(-1), was observed due to process. Mid IR spectral analysis was used to calculate the content of the epoxy groups as a function of crosslinking time and the crosslinking degree of resin. The amount of all the epoxy species was estimated from IR spectra to changes during the crosslinking kinetics of epichlorhydrin.
