| Résumé : |
The objective of the present study is the utilisation of agro-wastes, like Bhilawanut Shell Liquid (BSL) and Cashewnut Shell Liquid (CNSL) to develop surface coatings for the protection of bamboo surfaces from corrosive environments. As traditional bamboo coatings have the disadvantages of leachability and poor resistance to corrosive environment, it is necessary to develop alternate coatings with better adhesion properties for the protection of bamboo. BSL is an indigenous extract from the shells of Semecarpus anacardium and CNSL is a waste product obtained from the cashew industry. Both BSL and CNSL exhibit the unique properties of ortho dihydric phenol, which can be utilised profitably in the coatings industry. Surface coatings based on BSL and CNSL were prepared from formaldehyde, styrene, hexamine and epichlorohydrin. These coatings were applied on bamboo, and the performance of the coatings was evaluated by determining their physical, chemical and mechanical film properties. The coatings were also characterized by employing IR, NMR and scanning electron microscopical studies. |
