The present invention relates to a urethane resin composition containing a urethane resin (C) produced by reacting a polyol (A) with a polyisocyanate (B), the polyol (A) containing a polyether polyol (a1), which has an oxyethylene structure (a1-1) and an oxyalkylene structure (a1-2) other than the oxyethylene structure (a1-1), and a polyoxytetramethylene glycol and/or a polycarbonatediol (a3), wherein the polyether polyol has a ratio by mass [(a1-1)/(a1-2)] of the oxyethylene structure (a1-1) to the oxyalkylene structure (a1-2) in a range of 3/7 to 9/1, and the ratio by mass of the polyether polyol (a1) is 10% by mass to 50% by mass.Type: ApplicationFiled: May 24, 2011Publication date: May 30, 2013Applicant: DIC CORPORATIONInventors: Kazuhiko Chiyonobu, Hiroki Tanaka, Naotaka Gotoh, Miwa Ueguchi

Publication number: 20130131189Abstract: The present invention concerns new associative thickening agents belonging to the category of HEURs (Hydrophobically modified Ethylene oxide URethane). These products contain an original associative monomer with a base of alkyl cyclohexanol alkoxylates. Their thickening power is equal to or greater than that procured by HEUR associative thickening agents of the prior art containing grafted alkyl phenols. An efficient substitute product is therefore available, which is free of alkyl phenols, matching current market demand.Type: ApplicationFiled: November 8, 2012Publication date: May 23, 2013Applicant: COATEX S.A.S.Inventor: COATEX S.A.S.
