Publication number: 20030209826Abstract: A process for producing a molded article comprised of polyurethane is provided, comprising the steps of pouring or injecting a liquid molding material into a mold under the condition that the contact angle between the liquid molding material and the inner surface of the mold is adjusted to not more than 30° by applying the surface-treating agent to the inner surface of the mold, and curing the liquid molding material. A surface-treating agent is also provided which reduces the contact angle between the liquid molding material and a flat plate made of the same material as the mold to not more than 30°. when the surface-treating agent is applied to the flat plate and the liquid molding material is dropped thereon.Type: ApplicationFiled: June 20, 2003Publication date: November 13, 2003Applicant: KAO CORPORATION.Inventors: Makoto Okubo, Kazuhiko Kiuchi, Ryoichi Hashimoto, Takayuki Nomura, Masahiro Mori, Kenichi Miyamoto

Patent number: 5932628Abstract: The binder composition for the production of molds of the present invention comprises a binder obtained by polycondensation of polycondensable components comprising as major components furfuryl alcohol, urea, and an aldehyde. In the binder contained in the binder composition for the production of molds, the difference ?A-B! between the weight % of charged furfuryl alcohol (A) based on the weight of the binder and the weight % of unreacted furfuryl alcohol (B) based on the weight of the binder is 5.0 to 60.0. When the binder composition for the production of molds of the present invention is used, the curing of the binder is further accelerated without deteriorating the working atmosphere.Type: GrantFiled: February 19, 1997Date of Patent: August 3, 1999Assignee: Kao CorporationInventors: Kazuhiko Kiuchi, Masayuki Kato, Masuo Sawa, Shigeo Nakai
