A clear solution of nitrocellulose in an organic solvent, usually acetone, ethyl acetate or diethyl ether (collodion), used to coat metal products, documents, etc. to protect them from aggressive environments, as well as for marking. After drying, it forms a strong, gas- and waterproof film.
Organic dyes are added to give color to the varnish.
The main application of zaponlak in electronics is the coating of electrical connections soldered with tin-lead solders. The need for coating is due to the fact that the main cause of failures of equipment with surface mounting of electronic elements over time - ring microcracks at the place of soldering - by themselves are not capable of causing a breakdown in electrical contact and failure of the equipment, but penetration of water vapor into the crack with their subsequent condensation causes over time, the formation of films of poorly conducting oxides of tin and lead, which increases the electrical resistance of the contact. Zaponlak applied to a soldered joint forms a strong, elastic film on its surface, which prevents the development of corrosion in cracks. It also serves as a marker for visual quality control of the soldering - the controller notes the solderings he has checked. The zaponlak used for this is dyed crimson, green or dark purple by adding synthetic organic dyes to the nitrocellulose solution.
Zaponlak has limited use in lighting engineering - it is used to paint bulbs of low-power incandescent lamps, for example, in Christmas tree electric garlands.
Tsaponlak is used in the manufacture of Christmas tree and other decorations, in modeling, etc.
It is also used in engineering for fixing (locking) threaded connections to prevent spontaneous unscrewing when exposed to vibrations.
