Method For Achieving Recoat Adhesion Over A Fluorinated Topcoat

View page
US Patent:
6933005, Aug 23, 2005
Filed:
Sep 22, 2003
Appl. No.:
10/668989
Inventors:
William F. Graham - Wayne PA, US
Douglas Robert Anton - Wilmington DE, US
Jeffery W. Johnson - Rochester Hills MI, US
Michael Joseph Michalczyk - Wilmington DE, US
Sape Kwesi Quashie - Southfield MI, US
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
B05D001/38
B05D003/00
B05D007/26
US Classification:
427142, 427258, 427387, 4274071, 525453, 525901
Abstract:
A method for repairing a basecoat/clearcoat finish or coating comprised of a fluorinated organosilane topcoat. A fluorourethane star polyester additive is added to the fluorinated organosilane topcoat composition to improve recoat adhesion with the repair basecoat.

US Patent:
7288282, Oct 30, 2007
Filed:
Sep 22, 2003
Appl. No.:
10/668991
Inventors:
William F. Graham - Wilmington PA, US
Douglas Robert Anton - Wilmington DE, US
Jeffery W. Johnson - Rochester Hills MI, US
Michael Joseph Michalczyk - Wilmington DE, US
Sape Kwesi Quashie - Southfield MI, US
Assignee:
E. I. du Pont de Nemours and Company - Wilmington DE
International Classification:
B05D 3/00
B05D 7/26
US Classification:
427142, 427258, 427387, 525199, 5253311, 5253305, 524520, 524589, 524588, 526242, 526279
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.

US Patent:
60204990, Feb 1, 2000
Filed:
Jun 5, 1998
Appl. No.:
9/092156
Inventors:
Neville E. Drysdale - Newark DE
Mike Fryd - Moorestown NJ
Sape Quashie - Southfield MI
Assignee:
E. I. du Pont Nemours and Company - Wilmington DE
International Classification:
C07D32100
US Classification:
549228
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.
