  • Scratch resistant refinish clearcoat
    Patent number: 9309434
    Abstract: Scratch resistance and/or reflow of a refinish topcoat is improved by preparing the topcoat from a refinish topcoat coating composition comprising an unsaturated fatty acid ester polyol that does not undergo oxidative cure when the applied refinish topcoat coating composition is cured.
    Type: Grant
    Filed: October 19, 2011
    Date of Patent: April 12, 2016
    Assignee: BASF Coatings GmbH
    Inventors: Ali Rihan, Anthony J. Tye

  • Fast drying clearcoat refinish composition
    Patent number: 7446149
    Abstract: A refinish clearcoat composition includes an hydroxyl-functional acrylic polymer. The acrylic polymer has a number average molecular weight of at least about 5000 and is polymerized using at least about 45% by weight cycloaliphatic monomer, based on total monomer weight polymerized. The clearcoat composition is fast drying. Optionally, the clearcoat is cured by low temperature baking. The cured clearcoat surface may be taped without leaving tape marks as soon as the substrate is cooled. The cured clearcoat may undergo wet sanding after baking as soon as the part is cooled, and can then be buffed back to a high gloss finish after sanding and washing.
