|Title:||Preparation and Characterization of Penta Alkyds Based on Mahua Oil|
Tiwari, S K
|Abstract:||A medium oil length alkyd resin is prepared from mahua oil (a non-traditional oil), pentaerythritol and phthalic anhydride. The alkyd was characterized by IR analysis. Other properties viz. , viscosity, specific gravity, acid number, saponification value etc. were determined. Film characteristics of the resin like drying time, thickness, scratch hardness, impact resistance and adhesion were also assessed. The performance of the resin was found to be comparable to a commercial resin. Penta alkyd developed using mahua is of non-drying nature. It can be used as a baking system by curing with melamine at 140oC for 4 hr. The baked film offers good mechanical properties as well as resistance to water and alkali. Combination of ester gum with mahua alkyd gives an air dying resin.|
