Publication number: 20070270567Abstract: A two component polyurethane adhesive composition having one or more polyols as a first component and one or more isocyanates as a second component. The composition also comprises one or more catalysts and one or more blocking agents to delay the curing reaction. The composition provides long open time, improved wet out of the substrates to be bonded, a rapid cure rate and excellent final bond performance at room and elevated temperatures. Optional ingredients, such as fillers, chain extenders and plasticizers may be added as desired. In one embodiment, the catalyst is a tin catalyst such as dibutyl tin dilaurate which may optionally be combined with other catalysts such as tertiary amines. The blocking agent in one embodiment is 8-hydroxyquinoline.Type: ApplicationFiled: May 19, 2006Publication date: November 22, 2007Inventor: Wu Suen

Patent number: 7279543Abstract: An anti-bacterial polymer of the present invention consists of a vapor deposition-polymerization reaction product of a diaminobenzoic acid monomer or halogen atom-containing diamine monomer and a monomer reactive with these monomers. The anti-bacterial polymer can be prepared by a method, which comprises the step of subjecting a gas obtained by evaporating a diaminobenzoic acid monomer or halogen atom-containing diamine monomer and a gas obtained by evaporating a monomer reactive with these monomers to vapor deposition-polymerization, in a vacuum, to thus form an anti-bacterial polymer. The method permits the formation of a film having a desired thickness even on the surface having a complicated shape such as the surface of, for instance, a heat exchanger.Type: GrantFiled: September 5, 2003Date of Patent: October 9, 2007Assignee: Ulvac, Inc.Inventors: Hagane Irikura, Yoshikazu Takahashi
