Abstract

In this study, different samples of alkyd resins based on Citrullus colocynthis seed oil (CCSO)—which has a high content of linoleic acid—were prepared as a renewable raw material. Short (I), medium (II), and long (III) alkyd resins were synthesized using oil, glycerol, and phthalic anhydride (PA) in different proportions. Prunus mahaleb seed oil (PMSO), which contains conjugated linolenic acid, was blended with CCSO in different proportions to examine the effect of PMSO on the film properties of alkyd resins (IV and V). All synthesized resins were characterized by FTIR and 1H NMR spectroscopic analysis. These resins were also cured by an epoxy resin and their film properties (pencil hardness, adhesion, gloss, and chemical resistance) were determined. Analysis of these alkyds reveals that CCSO can be used as a new potential raw material for coating applications.
