Castor oil (C) was reacted with profitable epoxy resin (E) (diglycidylether of bisphenol-A, DGEBF) at a range of mole ratios. The consequential products (Castor oil- Epoxy resin) were nominated as CEs. Isocyanate terminated castor oil Polyurethane (ICOPU) was prepared by reaction of castor oil and various proportion of Isophoren diisocyanate. A commercial alkyd resin was blended with various proportions of CEs and ICOPU. A unique solvent system, which shows a one – phase clear solution and a clear coat of binder system, was used. All the blends were applied on mild steel panels and characterized for drying time, adhesion, flexibility, hardness, impact resistance and chemical resistance properties.
