TL;DR: A thermolabile substance was discovered in the latex of the Japanese lacquer tree (Rhus vernicifera) which was responsible for the darkening and hardening of the lacquer.
Abstract: IN 1883 Yoshida1 discovered, in the latex of the Japanese lacquer tree (Rhus vernicifera), a thermolabile substance which was responsible for the darkening and hardening of the lacquer.
TL;DR: The analysis of components, modification, synthesis, processing, and applications of Oriental lacquer are reviewed in this article, where the structures and biological activities of lacquer polysaccharides, lipid components including urushiol, laccol, and thitsiol are discussed.
Abstract: The analysis of components, modification, synthesis, processing, and applications of Oriental lacquer are reviewed in this paper. The structures and biological activities of lacquer polysaccharides, lipid components including urushiol, laccol, and thitsiol, the structure and activities of the lacquer enzyme laccase and the advantages of fast drying of refined lacquer over raw lacquer as well as hybrid lacquer are discussed. Lacquer was synthesized based on the components of lacquer sap and a detailed discussion of the enzyme polymerization and auto-oxidation of lacquer are also included. In addition, an overview of lacquerware processing and possible applications of lacquer in industry will be presented.
TL;DR: This spraying method with lacquer was found to be an excellent alternative for the fabrication of paper-based devices due to its ease of use, affordability and simplicity.
TL;DR: In this paper, the performance of lacquer wood activated carbon prepared by different activation methods and temperature (300, 400, 500, 600, 700, and 800°C) was studied, and the influence on its electrochemical properties provided valuable guidance for the high-efficient energy utilization of Lacquer wood.
TL;DR: Water dispersible polyisocyanate mixtures as discussed by the authors were used in the preparation of polyurethane plastics or as a cross-linking agent for water soluble or water dispersible binders.
Abstract: Water dispersible polyisocyanate mixtures, which are prepared by reacting lacquer polyisocyanates with hydrophilic, monohydric polyether ester alcohols obtained by reacting monohydric hydrophilic polyether alcohols with e-caprolactone at an NCO/OH equivalent ratio of 4:1 to 120:1, and their use in the preparation of polyurethane plastics or as a cross-linking agent for water soluble or water dispersible lacquer binders.
