A non-aqueous stripping composition and a method of stripping an organic coating from a substrate

Abstract

To achieve efficient stripping of organic coatings from sensitive substrate without affecting the substrate surface, a novel non-aqueous stripping composition and method are provided. The stripping composition comprises: A. at least one high-boiling solvent selected from the group, consisting of alcohols having general chemical formula R—OH, wherein R is a C4-C30 hydrocarbon group, wherein the high-boiling solvent has a boiling point of at least 100° C.; B— at least one high-boiling co-solvent selected from the group, consisting of high-boiling glycols, glycol ethers and amine compounds, wherein the high-boiling co-solvent has a boiling point of at least 100° C.; and C— at least one pH-active agent either selected from the group, consisting of acid compounds or selected from the group, consisting of hydroxide compounds.
