Abstract:
Water soluble paint remover compositions for the removal of uncured paint are disclosed which avoid the use of toxic organic solvent, in particular, methylene chloride. The inventive compositions comprise an organic carboxylic acid, N-methyl-2-pyrrolidone, and an alkylen glycol ether. Methods for use of the compositions are also disclosed.
Abstract:
The present invention provides a method of substantially dissolving contaminants or removing contaminants from the surface of a substrate. The method comprises the step of using a solvent of formula (I), wherein R is a hydrocarbon having 1 to 3 carbon atoms and A and B are the same or different and partially fluorinated or perfluorinated alkyl groups having 1 to 2 carbon atoms.
Abstract:
Disclosed is the use of 2-ethylhexyl esters of fatty acids, optionally mixed with emulsifiers, solubilizers, corrosion inhibitors and/or water, as low-viscosity agents for the cold cleaning of metal surfaces contaminated mainly with oil. Such agents are non-toxic when inhaled and completely biodegradable.
