Douglas H. Larrow has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6794442
    Abstract: A refinish basecoat composition includes at least one pigment and an hydroxyl-functional acrylic polymer. The acrylic polymer has a number average molecular weight of at least about 6000 and is polymerized using at least about 45% by weight cycloaliphatic monomer, based on total monomer weight polymerized. A mixer system that can be used to prepare the refinish basecoat has a plurality of color components, each independently including at least one pigment dispersed by the hydroxyl-functional acrylic polymer, and a pigment-free component containing the hydroxyl-functional acrylic polymer.
    Type: Grant
    Filed: June 21, 2001
    Date of Patent: September 21, 2004
    Assignee: BASF Corporation

  • Patent number: 6087436
    Abstract: Air-dry refinish primer compositions containing microparticles have been found to exhibit superior air-dry properties as well as being resistant to solvent attack when a primer-surfacer or topcoat is applied after a short (30 minute or less) dry time of the primer composition.
