The paints only dry by evaporation of the solvent (nitrocellulose, alcohol, chlorinated rubber, etc.) Can be removed by simply immersing in the appropriate solvent. Chemically crosslinked paints (epoxides, polyesters, MIXs, polyurethanes, alkyds) are soluble in special solvents, mostly higher aliphatic or aromatic hydrocarbons. The rate of softening of the paint then depends on the type of paint binder, the thickness of the lacquer layer, the temperature of the solvent. Paint residues must be removed mechanically.
