Nitrocellulose lacquers
Relative to the slow-drying paints and lacquers that preceded them, faster-drying and more durable solvent-based lacquers that contain nitrocellulose, a resin obtained from the nitration of cotton and other cellulosic materials, were developed in the early 1920s, and extensively used in the automobile industry for the next 30 years. Prior to their introduction, mass-produced automotive finishes were limited in colour, damaged easily, and took a long time to dry,[14]:295–301 with Japan Blackbeing the fastest drying and thus the most economical to use. In 1923, General Motors' Oakland brand automobile was the first to introduce one of the new fast-drying nitrocellulose lacquers, a bright blue, produced by DuPont under their Ducotradename.[14]:295–301 In 1924 the other GM makes followed suit, and by 1925 nitrocellulose lacquers were thoroughly disrupting[clarification needed] the traditional paint business for automobiles, appliances, furniture, musical instruments, caskets, and other products.[14]:295–301

Nitrocellulose lacquers are also used to make firework fuses waterproof. The nitrocellulose and other resins and plasticizers are dissolved in the solvent, and each coat of lacquer dissolves some of the previous coat. These lacquers were a huge improvement over earlier automobile and furniture finishes, both in ease of application and in colour retention. The preferred method of applying quick-drying lacquers is by spraying, and the development of nitrocellulose lacquers led to the first extensive use of spray guns. Nitrocellulose lacquers produce a hard yet flexible, durable finish that can be polished to a high sheen. Drawbacks of these lacquers include the hazardous nature of the solvent, which is flammable and toxic, and the hazards of nitrocellulose in the manufacturing process. Lacquer grade of soluble nitrocellulose is closely related to the more highly nitrated form which is used to make explosives. They become relatively non-toxic after approximately a month since, at this point, the lacquer has evaporated most of the solvents used in its production.
