Abstract
Compounded polymeric compositions containing processed paint sludge putty as a replacement for polymeric components are provided. The paint sludge comprises from about 5 to 90% by weight of the total compounded polymeric composition and may be decatalyzed so that it contains uncured polymer for use in a variety of compositions including pressure sensitive sealants, caulking sealants, automotive sealants, polyvinyl chloride plastics, rubbers and asphalt cement coatings.
