  • Publication number: 20110283908
    Abstract: High-opacity polyurethane resins are produced by polymerization of polyisocyanates with polymeric polyols and subsequent chain extension with polyamines. The resins provide high-opacity inks when formulated with white pigments, which maintain good extrusion and adhesive lamination bonding strength properties. The inks are useful in flexographic and/or gravure printing processes, particularly as back-up for laminated packaging.

  • Patent number: 8062709
    Abstract: A process for preparing polyurethane carpet backings uses a filled polyurethane-forming composition that contains a mixture of certain metal acetylacetonate and sulfur-containing organotin catalysts. The mixture of catalysts is particularly beneficial in instances where the composition is processed at temperatures of above 30 to about 500 C, as long pot life is provided together with a rapid thermally-induced cure.

  • Publication number: 20110237758
    Abstract: The present invention provides a urethane-forming reaction catalyst which is useful for catalyzing a reaction between an isocyanate compound, in particular, an aliphatic isocyanate and a hydroxyl group-containing compound to form a urethane material, which does not affect the performance of the urethane material, and which can be easily removed from the resulting urethane material, and a method for producing a metal compound-free urethane material using the urethane-forming reaction catalyst. The catalyst of the present invention is a urethane-forming reaction catalyst for producing a urethane material by allowing a hydroxyl group-containing compound to react with an isocyanate compound, the catalyst being at least one solid acid catalyst selected from the group consisting of a (A) composite metal oxide in which a metal oxide (A-2) or a non-metal compound (A-3) is carried on a surface of a metal oxide carrier (A-1), (B) zeolite, and a (C) heteropoly acid.

  • Publication number: 20110126982
    Abstract: The present invention relates to moisture curable reactive adhesive compositions containing a visual indicator and methods for using these compositions. Specifically, the invention relates to a two part moisture curable reactive adhesive system, where one part consists of a prepolymer with moisture reactive groups and the second part consists of catalyst, a visual indicator and water. The presence of the indicator allows the combination of the two part system to be visible to the naked eye. The visible indicator ensures that the two part system is combined uniformly and completely to a desired substrate, but it does not interfere with the crosslinking reaction.
