Abstract
Abstract Compositions for reflowing organic surfaces, such as paints and polystyrene, have been discovered which contain by volume 50 to 90 percent of a liquid chlorinated aliphatic hydrocarbon, 5 to 30 percent of a liquid ketone or alcohol, 2 to 20 percent of glycol ether alkanoate and 0 to 30 percent of an alkyl alkanoate, all of such components having a boiling point below 200* C.
