Cellulose nitrate lacquer
Also known as Nitro lacquer, CN-Lack, NC-Lack. In terms of quantity, cellulose nitrate lacquers still represent the greatest amount of furniture lacquers. The mostly easy to handle NC lacquers dry by purely physical means by flashing off the organic solvent. The dried coating can be dissolved at any time with the appropriate solvent. This allows problem-free repair or restoration. The solids content is generally between 15 and 30%. In the current climate, the relatively high proportion of solvent caused by this leads directly to conflicts with the Laws on Emissions Control (TA-Luft/VOC).
The resistance of NC coated surfaces is acceptable for furniture for interior decoration both in terms of chemical and mechanical stresses, but insufficient for kitchen,
bathroom, office furniture and blockboard.
