Zusammenfassung:	ENCAPSULATING SEALANT COMPOSITIONS FOR FRIABLE INSULATION MATERIALS Abstract of the Disclosure A penetrating sealant composition useful for encapsu-lating a friable material which is designed to be stored in two parts, one of said parts comprising an aqueous silicate solution comprising a water soluble alkali metal silicate such as potassium silicate or a mixture of potassium silicate and sodium silicate and a cationic or nonionic surfactant and the other parts 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 having a solids content between 20 and 65 weight percent. The sealant composition is particularly useful for friable asbestos-containing materials and the cured sealant provides a physically tough flexible barrier.
