Abstract
There is disclosed a composition of matter useful for stripping paint and varnish from substrates comprised of the conventional industrial chlorinated solvents, e.g. methylene chloride (dichloromethane) solvent and a wax, such as paraffin wax, which composition is improved by the addition thereto of a novel class of evaporation retarding chemicals resulting in a far more effective stripping action and a much improved environmentally desirable composition, with respect to the concentration of methylene chloride in the ambient atmosphere surrounding the work situs. The evaporation retarding chemical can be a surfactant, a resin plasticizer or ethylene or propylene carbonate.
