Nowadays, the use of non‐traditional vegetable oils as polymer precursors is the subject of growing interest because of increasing price of crude oil and eco‐friendly approach. In this context, present work reports the synthesis of mahua oil fatty amide (MFA) from the mahua oil. The synthesized MFA was characterized by chemical and spectroscopic methods and utilized as a hydroxyl component of “two‐component polyurethane (2K‐PU)” system. The prepared 2K‐PU was used as wood protective coating material. The coating performance of the formulated 2K‐PU was evaluated by the measurement of mechanical, thermal and antimicrobial properties as well as water and chemical resistance. The study reveals that MFA can be used as the hydroxyl component in 2K‐PU coating system. MFA was derived from a relatively economical and renewable resource and the use of MFA can substantially reduce the cost of polyurethane coating formulations.

In the current scenario, the demand for renewable resources is increasing day by day due to numerous factors. In view of this, current work represents the preparation of wood protective polyurethane (PU) coatings from mahua oil. Mahua oil was used as a starting material for the synthesis of fatty amide by base catalyzed aminolysis reaction. The synthesized fatty amide was converted into the polyetheramide polyols by a condensation reaction with bisphenol C. The structure of the synthesized products was confirmed by the attenuated total reflection‐Fourier transform infrared and 1H‐NMR spectroscopy. The synthesized polyetheramide polyols were used as precursors for the preparation of PUs and the prepared PUs were applied on the wood surface as a protective coating. The coating performance of the PUs was evaluated by the measurement of mechanical, thermal, and microbial properties as well as water, solvent, and chemical resistance. The coating performance revealed that mahua oil can be used as a renewable resource for the preparation of wood protective PUs. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46722.
