Abstract

Liquid, solvent-free, aqueous compositions for the removal of film-forming polymeric protective coatings. The compositions contain a combination of alkanolamines and hydrotropic substances acting as solution promoters. Optionally, pH-regulating acids, thickeners, surfactants, corrosion inhibitors, biocides and/or dyes are added.
