ABSTRACT:
This invention involves a novel paint formulation comprising a phosphate or metal sulfide heavy metal reactive compound, a binder, a solubilizing compound and a buffer which acts as a carrier for heavy metal reactive chemicals so that when this novel paint is applied to a heavy metal painted surface and both are subsequently removed, the heavy metal paint waste is rendered non-hazardous under the TCLP test.
