The crosslinking of epoxy resins can be achieved through two different reaction mechanisms, polymerization by addition and by steps .
Sung, C. Samples crosslinked at room temperature were stored in a desiccator.
Conclusions A new solvent free epoxy formulation based on the use of aliphatic and cycloaliphatic polyamine adducts as the hardeners was analyzed and characterized by fast FT-IR spectroscopy.
The rates of cure of bisphenol A based epoxy resin and its mixtures with diethylene glycol based epoxy resin with maleic anhydride and BF3 etherate accelerator were measured from the dependences of degree of cure with time, using GPC, DSC and IR spectroscopy .

Materials characterization by thermomechanical analysis. The IR spectra of polyamine adducts films were performed between two quartz plates 5 x 2 x 0. Abstract: 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.

|Moreover, a large decrease in the IR band intensity of GY resin at about 3, cm-1 was observed.
As the crosslinking proceeded, the primary amine groups in polyamine adduct are converted to secondary and the tertiary amines. Besides, IR is available especially for the crosslinking analysis, and it has been used for the estimation of both epoxy and hydroxyl functional groups in polymeric materials. Mikes, F.
