Abstract
A composition and method for stripping and cleaning organic coatings from substrates, comprising a solution of high-boiling alcohols, preferably polyglycols, a surfactant, preferably a nonylphenol ethoxylate, and an alkali metal hydroxide, said composition being essentially free of any amines. The composition aggressively and effectively strips paints and other organic coatings without harming underlying substrates damaged by prior art strippers, over conventional or lower time periods, and at conventional or lower temperatures. One embodiment of the invention comprises from about 40% to about 98.9% by weight of a high-boiling alcohol; from about 1% to about 60% of a non-ionic surfactant; and from about 0.1% to about 10% of an alkali hydroxide or mixture of alkali hydroxide.
