Abstract
Described is a composition capable of stripping protective and/or decorative coatings from a substrate comprising: a major amount of a chlorinated hydrocarbon having from one to four carbon atoms; a minor amount of a carboxylic acid accelerator useful for accelerating removal of the coating; and an effective amount of a penetrating nitrogen containing amine oxide surfactant. The compositions are effective for stripping protective coatings as acrylic resins, epoxy resins, vinyl resins, polyester resins and polyurethane resins at ambient temperature.
Claims17
A liquid composition capable of removing protective and/or decorative organic polymerized film coatings from a substrate comprising:
- (a) a major amount of a chlorinated hydrocarbon of from one to four carbon atoms;
- (b) a minor amount of an acid accelerator useful for accelerating the removal of the coating, which acid accelerator is a combination of a halogenated carboxylic acid and a carboxylic acid in a weight ratio of from about 0.5 to 5:1 halogenated carboxylic acid:
- carboxylic acid;
- and
- (c) an effective amount of a penetrating nitrogen containing amine oxide surfactant selected fro the group consisting of dimethyl cocoamine oxide, Bis (2-hydroxyethyl) cocoamine oxide, dimethyl-hexadecylamine oxide, dimethyl (hydrogenated tallow) amine oxide, Bis (2-hydroxyethyl) tallowamine oxide, cocoamidopropyl dimethylamine oxide, lauryl dimethylamine oxide, fatty acid amido alkyldimethylamine oxide, cetyl dimethylamine oxide, myristylcetyl dimethylamine oxide, myristyl dimethylamine oxide, stearyl dimethylamine oxide, alkyl dialkoxy amine oxides, alykl dialkoxyether amine oxides, and mixtures thereof.
