atmospheric contamination by residual hazardous particles remaining on a substrate following removal from the substrate of a layer of material containing such particles is substantially reduced by coating the substrate with certain aqueous coating compositions which produce tacky films on drying . for example , the health hazard from airborne asbestos fibers remaining attached to a substrate from which a layer of asbestos - containing material has been removed is substantially reduced by coating the substrate with an aqueous latex composition containing certain carboxylated butadiene styrene polymers .
