Asbestos Removal

Grace has introduced a product that it says is the first to chemically destroy asbestos in installed fireproofing. The process is reported to be only 33% of the cost of conventional techniques. The really interesting feature of this technology is that it uses a foam delivery system. The foam contains an inorganic acid, as well as a fluorine source, which are used to degrade magnesium and silica-containing asbestos components. The product is NOT commercially available any longer. The patent covering this technology has been issued:
