  • Method for treating paint sludge
    Patent number: 5922834
    Abstract: A method of treating paint sludge containing uncured polymer resin, water and/or solvent is provided in which a paint sludge putty is formed which may be used as a replacement for polymeric components used to form compounded polymeric compositions. The treated paint sludge putty or powder comprises from about 5 to 90% by weight of the total compounded polymeric composition and may be used in a variety of compositions including pressure sensitive sealants, caulking sealants, automotive sealants, polyvinyl chloride plastics, rubbers and asphalt cement coatings, and waterbased sealers and coatings.
    Type: Grant
    Filed: July 14, 1997
    Date of Patent: July 13, 1999
    Assignee: Aster, Inc.
    Inventors: Michael Joseph Gerace, Sevilla C. Gamboa, Yasminka S. Landaburu
  • Compounded polymeric compositions utilizing processed paint sludge as a replacement for polymeric components
    Patent number: 5880218
    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.

  • Method of making sludge powder and sealant from paint sludge and sludge powder and sealant compositions produced thereby
    Patent number: 5254263
    Abstract: A sludge powder and sealant are prepared from paint sludge. A sludge powder is generated from a paint sludge having a volatiles content of 0-50% by weight by adding a processing filler thereto. A sealant composition is prepared by thereafter or concurrently therewith adding sealant ingredients including polymer, plasticizer, curative, and other sealant ingredients such as an adhesion promoter and sealant filler materials to the sludge powder. Alternatively, a sealant composition may be prepared by adding a paint sludge having a volatiles content of 0-50% by weight to the sealant ingredients, which may include a processing filler.
