Alkyd resin is a key ingredient of all surface-coating products like paints, primers, adhesives, printing ink etc. Conventional alkyd resin uses petroleum-based products (50-70%) like phthalic anhydride (35-50%) and organic solvents (30%). In the present work, a novel alkyd resin was developed containing renewable vegetable product (50-70%) petroleum based products (25%).

In the present work, a novel alkyd resin was developed containing renewable vegetable product (50-70%) petroleum based products (25%). Volatile organic compounds (VOC) content of conventional alkyd resin is 40% while the new alkyd resin was 14%. The novel alkyd resin manufacturing temperature was around 200 oC for 7-8 hours as compared to conventional resin (225-240oC for 12 hours) thus saving energy and time. The physicochemical and film properties of resin have been studied and compared with commercial sample. The cost of the present product is less than the conventional product.
