Patent 7344780 was granted and assigned to Daikin Industries, Ltd. on March, 2008 by the United States Patent and Trademark Office.
An amino group-containing metal compound such as a coupling agent having an amino group is dispersed in a fluoroelastomer coating composition comprising a fluoroelastomer and a polyol curing agent which are dissolved or dispersed in a liquid medium. The resulting fluoroelastomer coating composition can form an elastomer coating layer directly on a metal surface using no primer, and improve antifreeze resistance and deterioration of the coating film after compression at high temperatures for a long time.
