A rapid determination method of free toluene diisocyanante(TDI) content in coating solidifying agent was developed by near infrared spectroscopy(NIR),with GC analysis values as the reference.NIR transmission spectrum of the solidifying agent was first collected.Among the 120 samples analyzed,109 representative samples were selected to establish TDI content of predictive models with the NIR wave numbers between 7320~7250 cm^-1 and 8485~8370 cm^-1,by the partial least squares(PLS) and fully-interactive authentication methods.The results showed that the free TDI contents in the solidifying agent of and the nearinfrared spectra correlate very well.The calibration set RMSEC was 0.0815 and validation set RMSEP was 0.0715.This proofed the performance of the working model,and indicated that NIR spectroscopy can be used for fast and accurate determination of TDI content in solidifying agent samples.
