Alkyd/melamine resin mixtures are mainly used in industrial baking enamels. The effects of the alkyd/butylated melamine resin ratio (from 90/10 to 50/50) and curing temperature (from 110 to 180?C) on the crosslinking and properties of the coating are presented in this paper. The curing reactions through functional groups of resins were monitored by FT-IR spectroscopy. The hardness, elasticity, degree of adherence and gloss were also determined. Optimal coating properties could be achieved with an alkyd/melamine resin ratio of 80/20, a curing temperature of 150?C and a curing time of 20 min.

The aim of this study is to characterize and identify the main biomarkers of food supplement PROMEN by analysis of plant ingredients comparatively with the final product. Alcoholic extracts of plants were prepared at 15% plant content and purified fractions were analyzed by FTIR screening. The fingerprint region (1000 to 1500 cm-1) indicated the presence of specific functional groups to identify and monitor the phenolic derivatives.
