ABSTRACT:
A coating remover comprised of a substantially uniform mixture of about 5 to 35 percent by weight of N-methyl-2-pyrrolidone and the balance comprised of a water-base carrier containing about 10 to 35 percent by weight organic surfactants therein so that when such liquid mixture is admixed with a gas, a substantially non-flammable, non-toxic, biodegradable and easily dispensible foam results which is characterized by a very high persistency and a very low volatility. This foam-type coating remover is useful for removing various paints, lacquers and other coatings or finishes, such as based on polyamide epoxy, cellulosic, vinyl or acrylic resins from various surfaces.
