چکیده انگلیسی
A lacquer sap hybridized with a silicate oligomer was synthesized, and its characteristics as a chrome-free corrosion protective coating were examined. A new absorption due to a siloxane structure appeared at 6.6 ppm in the NMR and at 1080 and 840 cm−1 in the IR spectra. The hybrid lacquer dries faster due to the reaction between the alkoxy radical of the silicate and hydroxyl of the urushiol, and had a higher glass transition than kurome and raw lacquers. In addition, the ability of the hybrid lacquer to prevent corrosion was comparable to the protection offered by chrome treatment.
