  • Solvent-free shellac coating composition
    Patent number: 11041094
    Abstract: A shellac coating composition for producing a shellac coating on a substrate comprises a fatty acid component, shellac and little or no volatile carrier liquid. Because the fatty acid inhibits the polymerization of the shellac when molten, the composition can be converted into a liquid state for coating purposes by simple heating, thereby eliminating the need for the volatile carrier liquid.
