Lacquer and lacquering


There have been developed various colored ethyl cellulose lacquers that compare favorably with standard nitrocellulose lacquers in physical tests. Ultra violet light caused rather pronounced darkening of the lighter colors such as white and light yellow, probably because of the use of high amounts of phenolic resin. Also because of the presence of relatively large amounts of phenolic resin, the cost was somewhat higher than a comparable nitrocellulose lacquer. Suggestions for further work and improvement are included. An ethyl cellulose lacquer has also been developed to be applied by spray or brush to ethyl cellulose plastics with a minimum amount of deleterious effects such as warping and decreasing of flexibility. Good color and gloss were obtained by use of proper resin combinations. With low ethyl cellulose content it was found necessary to clean the plastic surface mechanically because the remaining traces of die lubricant were apparently incompatible with the lacquer and caused subsequent flatting action and loss of gloss of the lacquer.
