Preparation, characterization and evaluation of jojoba seed oilmodified alkyd resins

Jojoba oil is a source of specially chemicals and its uses for industrial applications are gaining in adaptability and importance. Four different alkyd resins modified by various amount of jojoba seed oil (JSO) were prepared by an alcoholysis-polyesterification process. The effect of oil contents on properties such as the drying performance, thickness of film, solubility, viscosity and color of the alkyd resins was evaluated. The alkyd with the least oil content had the greatest viscosity and lightest colour as well as the most rapid drying property. The jojoba-alkyds were found to be comparable with commercial samples. Their films were resistance to water, alkali, acids and solvents as well as gloss %, adhesion, impact, hardness, bending and flexibility. Incorporation of jojoba oil into alkyd resin prooved to achieve good mechanical characteristics and high chemical resistance to these resins
