  • Patent number: 9011630
    Abstract: The present invention relates to curable compositions comprising at least one specific blocked amine, at least one surface-deactivated polyisocyanate that is solid at ambient temperature and optionally water or a water-producing substance. Compositions of this type are characterized by an extremely high storage stability as long as they are not heated. Hot curing compositions that cure with the action of heat can thus be produced. Heat-activated compositions can also be produced. When heat is applied the latter compositions are not cured but are activated so that they are able to cure under the influence of moisture. The curable compositions are particularly suitable for use as adhesives.

  • Patent number: 8178167
    Abstract: The invention relates to humidity hardening compounds containing at least one polyurethane polymer, P, exhibiting an isocyanate group, at least one polyimine ALD of Formula (I) of at least 22% by weight, in relation to the sum of the components of the compound which contain the isocyanate group, as well as, if necessary, a polyisocyanate oligomer OP. The humidity hardening compound is particularly suitable for providing coatings and linings. The use of the imines makes possible VOC-free or VOC-poor compounds, which is a substantial advantage for indoor applications.

  • Patent number: 8148475
    Abstract: Thermoplastic polyether polyurethane polymers are disclosed which are mixed with a crosslinking agent to achieve long run times in a melt spinning process to make elastic fibers. The crosslinking agent is preferably a polyether or polyester polyol reacted with a diisocyanate. A melt spinning process is also disclosed using a polyether polyurethane with a crosslinking agent. Long melt spinning run times can be achieved without experiencing excessive pressure buildup in the spinneret and fiber breakage. The thermoplastic polyether polyurethane polymers are made by reacting: (1) a blend of two or more hydroxyl terminated intermediates wherein one intermediate is a polyether intermediate and has a higher number average molecular weight than the other said polyether intermediates, and wherein the weighted average number average molecular weight of said blend is greater than 1200 Daltons; (2) at least one polyisocyanate; and (3) at least one hydroxyl terminated chain extender.
