The Trace of the Curing Process of Polyester/Mel amine Resins by FTIR

Abstract

Abstract: The curing process of polyester/melamine resins is investigated with FTIRin this paper.The peak at 913 cm^-1 assigned to deformation of methoxy and the peak at 3500 cm^-1 assigned to the stretching of hydroxyl were chosen as characteristic changes and the peak at 815 cm^-1 assigned to the vibration (out-of-plane) of triazine was chosen as the internal sign in the curing process of polyester/melamine resins.The results show that the numbers of hydroxyl groups, methoxy groups and carboxyl groups are gradually reduced and the numbers of ether bonds and carbonyl groups are gradually increased along with the curing process, which indicates that the curing is a complex process of crosslinking accompanied by self-condensation and esteri-fication.The curing speed of polyester/melamine resins is related to [OH]/[OCH₃] ratio.

Key words: Curing process, FTIR, Polytester/melamine resins
