The monitoring of the curing of plastic coatings on steel strip by infrared spectroscopy

Abstract

The transmission and specular reflectance mid infra-red spectra for three polymer systems used to coat mild steel are reported. The relative absorbance of selected candidate and reference peaks show a quantitative relationship with peak metal temperature, suggesting that mid-IR spectroscopy may be useful in assessing the degree of cure or plasticisation under industrial conditions.
