This work constructs a systematic microspectral analysis method for the molecular structure and molecular weight of coating resins, and the method has been applied in an unknown coating resin analysis successfully. The microspectral analysis method is based on the infrared vibrational spectroscopy （FT-IR）, nuclear magnetic resonancespeetroscopy（NMR）, pyrolysis gas chromatograph/mass spectrometer （PY-GC/MS）, and gel permeation chromatograph （GPC）. An import unknown coating resin was analyzed systematically, and the information about the molecular structure and molecular weight was revealed in detail. This work is very helpful and powerful for exploring the molecular structure and molecular weight of resins especially to coating resins.
