Publication number: 20110059252Abstract: The present invention is directed to two component coating compositions that cure under ambient conditions and more particularly to those having low VOC (volatile organic content) that are suitable for use in automotive refinish and Original Equipment Manufacturing (OEM) applications. The coating composition includes crosslinkable and crosslinking components, wherein the crosslinkable component includes a low polydispersity, low molecular weight copolymer having on an average 2 to 25 functional groups, such as hydroxyl, carboxyl, acetoacetoxy, primary and secondary amine, and epoxy. The copolymer is polymerized from a monomer mixture that includes one or more non-functional acrylate monomers and one or more functional methacrylate monomers provided with the functional groups. The crosslinking component includes polyisocyanate, polyamine, ketimine, melamine, epoxy, polyacid or a combination thereof. The invention is also directed to coating produced from the coating composition.Type: ApplicationFiled: November 15, 2010Publication date: March 10, 2011Applicant: E. I.

Patent number: 6410147Abstract: The present invention is directed to a low gloss crosslinkable coating composition that produces a low gloss coating upon cure. The crosslinkable composition includes a binder component and a crosslinking agent. The binder component includes a combination of at least two partially compatible crosslinkable components retained in an evaporable medium, such that the low gloss coating exhibits a 60° specular gloss that is at least 5% lower than gloss of coatings from coating compositions containing any one of the crosslinkable components. The low gloss coating composition of the present invention is especially suited for OEM and refinish automotive coating applications, such as automotive fenders and automotive side boards, typically used in sport utility vehicles.Type: GrantFiled: August 24, 2000Date of Patent: June 25, 2002Assignee: E. I. du Pont de Nemours and CompanyInventors: Ding-Yu Chung, Isidor Hazan, Donald Albert Paquet, Jr.
