Title: Penetrating compositions for wet removal of friable insulation materials

Abstract: A two component stripping composition useful for removing a friable material, one of said parts comprising an aqueous silicate solution comprising a water soluble metal silicate such as potassium silicate or a mixture of potassium silicate and sodium silicate and a cationic or nonionic surfactant and the other part comprising an acrylic polymer dispersion component comprising an acrylic polymer latex and a reagent that reacts with alkali metal silicate. The two parts are mixed to provide a blended composition ready for application having a solids content between 5 and 30 weight percent. The stripping composition is particularly useful for wet removal of friable asbestos-containing materials.
