Publication number: 20030069363Abstract: A method of preparing a curable coating and a method of curing the curable coating are disclosed. The curable composition from which the curable coating is prepared may be applied to the surface of a substrate in neat form or in aqueous medium to produce the coating. Curing of the curable coating may be accomplished by chemical generation of free radicals, by electrochemical generation of free radicals, by electron beam, by photochemical generation of free radicals, or by other electromagnetic irradiation.Type: ApplicationFiled: June 27, 2002Publication date: April 10, 2003Inventors: Gary David Greenblatt, Ward Thomas Brown, Michael Damian Bowe, Richard Foster Merritt, Ronald Scott Beckley, Barry Clifford Lange, Robert Wilczynski, David William Whitman, Martha Harbaugh Wolfersberger
