Structure of epoxy resin and hardener-Epoxy resin Manufacture

The structure of the epoxy resin and hardener, the infrared spectrum to provide the correct and fast identification method, which changes the molecular structure of the epoxy resin after curing was measured for the future, the functional group is an epoxy group of the epoxy resin, in the infrared spectrum location arise wavelength ~ 11μ. When the position of reacting with epoxy hardener is made ​​with a chemical structure of the ring-opening of the hydroxyl group, a hydroxyl group in the infrared spectra in the wavelength 3.1μ. Interest in 11μ and 3.1μ wavelength absorption peak position to detect changes in the size and condition of the epoxy curing proceed.
