Code 4439 applies to insureds that manufacture lacquers or spirit varnishes. Commercial nitrocellulose, usually wet with solvent (etheralcohol); natural resins, such as shellac, dammar, amber, copal; and synthetic resins such as ester gums, alkyd, and acrylate are received from others along with solvents or thinners such as alcohol, methanol, methyl isobutyl ketone, butyl acetate, toluene, and xylene. Spirit varnishes are solutions or dispersions of a resin or other film-forming substance in a volatile solvent which, when applied, harden by the evaporation of the solvent. Spirit varnishes are termed by the trade as cold-cut varnishes since they must be manufactured at a temperature that is below the flash point of the solvents used. Lacquers are, in some respects, comparable to spirit varnishes with the exception that more inflammable materials are used including nitrocellulose or pyroxylin. The mechanical work of manufacturing lacquers or spirit varnishes is, in general, a relatively simple process involving the placement of the required ingredients in a container or tank and agitating or stirring them until the resin is completely dispersed or cut. The resultant lacquer or spirit varnishes are then filled into drums or tank cars. Shipping regulations usually require red labels.
