Air drying alkyd resins from seed oil of kara wi la MC43

Abstract

Alkyd resins are a special family of polyesters which are mainly limited in application of surface coatings. The popularity of alkyd resins in surface coating industry throughout the world is due to cost effectiveness and versatility. Synthesis process of alkyd resins needs basically three different types of chemical constituents. One type of constituent is polyol with hydroxyl functionality greater than 2 and second constituent is polybasic acid or acid anhydride. Usually most of conventional alkyd recipes contain glycerol and pthalic anhydride. Fatty oils having considerable amount of unsaturated fatty acids are the third type of raw material for air drying alkyd resins.
