摘要： The present invention relates to compositions and their use for removing coatings from a substrate. The present invention is directed to a composition comprising (a) surfactants, (b) a sequestrant, and (c) a plasticizer/solvent. The composition may also contain (d) a hydrolyzing agent, e.g., a strong base compound and other additives. The composition of the present invention is free of chlorinated solvents, environmentally safe and user-friendly. In one embodiment, the composition further comprises a hydrolyzing agent present in an amount sufficient to reduce at least one of mechanical strength and adhesion between the coating and the substrate. Another embodiment of the invention is a method for removing paint or a coating from a substrate comprising applying a paint or coating removing effective amount of a composition comprising the compositions described herein to the substrate. Yet another embodiment of the invention is a method for cleaning a substrate comprising applying a cleaning effective amount of the composition of the present invention to the substrate. In one particular embodiment of the present invention, an immersion method for the removal of cured and uncured paint and coatings from ferrous metals is provided.
