Abstract

The sol-gel process is an original method for processing semi-organic thin films on steel sheets. Silicone coatings containing methyl and phenyl groups produced by the hydrolysis and condensation of alkoxysilanes have high thermal resistance and chemical stability. Though adhesion is minimal compared to other semi-organic coatings used on ferrous substrates, the addition of an appropriate organic polymer increases the flexibility and adhesion of the coating and enhances its capability for use on steel sheets. This adhesion improvement mechanism has been studied by specular and diffuse reflectance FTIR spectroscopy.
