Description
Solvents or Thinners are used in Paints and lacquers to reduce the viscosity or consistency of the material and facilitate the application of a uniform coating. They must be compatible with the oil or resin present. After application the solvent is no longer required and should evaporate completely from the film.
Another class of organic liquids used in paint industry is plasticizers their function is to remain permanently in the film of paint or varnish after application in order to impart elasticity and proper adhesion to it. In contradiction to the volatile solvents, plasticizers should be perfectly non-volatile, and should also be chemically stable, and not after in properties on prolonged exposure.
