Patent number: 8143345Abstract: Fluorinated polyurethanes and methods of making the same are provided. The fluorinated polyurethanes are useful for making polyurethane coating compositions for use in aerospace and other applications. The method includes a “split process” by which a hydroxypolyalkylenoxy derivative of a perfluoropolyoxyalkane is separately reacted with isocyanate to produce an isocyanate-terminated compound. The isocyanate-terminated compound is then reacted with an emulsifier to produce an acid- and hydroxyl-functional compound. The acid- and hydroxyl-functional compound is then reacted with isocyanate to form an acid-functional, isocyanate-terminated compound. The acid-functional, isocyanate-terminated compound is then reacted with at least one polyol to produce a higher molecular weight, acid- and hydroxyl-functional compound. Finally, the acid functional groups of the high molecular weight, acid- and hydroxyl-functional compound are neutralized to form a fluoro-urethane salt which is dispersed in water.Type: GrantFiled: December 8, 2008Date of Patent: March 27, 2012Assignee: PRC DeSoto International, Inc.Inventor: Razmik Boghossian
