Description
A fluid or paste formulation designed to remove dried paint or varnish. Commercial paint strippers generally use systems based on either solvents or alkalis. Most of the solvent strippers use Methylene chloride. It is an effective solvent that penetrates and swells oil, alkyd, and vinyl paints and most varnishes. However, it is not selective and will penetrate all paint and overpaint layers. Solvent strippers often contain co-solvents (Acetone, methanol), acid or alkali activators, surfactants, and thickeners. Alkali strippers react with the paint film to saponify the fatty acids in oil paints and hydrolyze proteins in casein paints. They may contain Sodium hydroxide, Sodium carbonate, Ammonium hydroxide, and/or Sodium silicate. While caustics are less toxic than halogenated solvents, they still react quickly with all paint layers. Some recent methods use weak organic acids, esters, gels, organic bases, enzymes, surfactants, and/or n-methyl-2-pyrrolidone to control the speed and depth of the paint removal (Wollbrink, 1993).
