  • Method for achieving recoat adhesion over a fluorinated topcoat
    Publication number: 20050064202
    Abstract: A method for repairing a basecoat/clearcoat finish or coating comprised of a fluorinated organosilane topcoat. A fluorinated urethane additive is added to the fluorinated organosilane topcoat composition to improve recoat adhesion with the repair basecoat.
    Type: Application

  • Coating compositions containing a fluorinated organosilane polymer
    Publication number: 20050065271
    Abstract: A coating composition containing a film-forming organosilane polymer, optionally a non-aqueous dispersed polymer, and a crosslinking agent selected from one or both of an organic polyisocyanate and melamine crosslinker. Fluorine functionalities are incorporated in the organosilane polymer to enhance soil resistance and cleanability. The coating composition can be used as a clearcoat over a conventional pigmented basecoat. The coating composition provides improved soil resistance and cleanability.

  • Cyclic carbonates and their reactions with amines
    Patent number: 6228979
    Abstract: Six-membered cyclic carbonates (2-oxo-1,3-ioxanes) in which keto or carbohydrocarbyloxy groups are bound to the 5 position of the ring are disclosed. They react surprising quickly with primary or secondary cyclic amines, and the novel product hydroxyurethanes are usefull as reactive diluents.
    Type: Grant
    Filed: December 13, 1999
    Date of Patent: May 8, 2001
    Assignee: E. I. du Pont de Nemours and Company
    Inventors: Neville E. Drysdale, Mike Fryd, Sapé Quashie
  • Cyclic carbonates and their reactions with amines
    Patent number: 6020499
    Abstract: Six-membered cyclic carbonates (2-oxo-1,3-dioxanes) in which keto or carbohydrocarbyloxy groups are bound to the 5 position of the ring are disclosed. They react surprising quickly with primary or secondary cyclic amines, and the novel product hydroxyurethanes are useful as reactive diluents.
