  • Polyisocyanate adhesive and sealant systems
    Patent number: 5981683
    Abstract: Improved sealants and adhesives derived from polyisocyanates having aromatically linked -NCO groups are cured at ambient temperatures when combined with a curing agent comprising an imino- and enamino-functional compound. These two component resin systems may be employed in fabricating multi-substrate laminates, especially those comprising lignocellulosic and cellulosic materials, such as wood and paper.

  • Polymeric foams
    Patent number: 5730896
    Abstract: A method the preparation of rigid foams by reacting an organic polyisocyanate with an isocyanate-reactive material in the presence of a blowing promoter characterised in that the isocyanate-reactive material comprises at least one isocyanate-reactive cyclic carbonate or isocyanate-reactive cyclic urea, the reaction being performed in the presence of an inert insoluble organic liquid which is present as the dispersed phase of an emulsion or a microemulsion, and in the presence of a metal salt catalyst.

  • Isocyanate-reactive compositions containing internal mold release agents
    Patent number: 5710231
    Abstract: An isocyanate-reactive composition is provided which comprises:(a) at least one compound having a plurality of isocyanate-reactive groups; and(b) a fatty polyamine having the formula:R.sup.1 --(NH--R.sup.2).sub.x --NH.sub.2wherein R.sup.1 is an alkyl group containing 8 to 40 carbon atoms, R.sup.2 is a divalent linking group containing 1 to 8 carbon atoms and x has a value of 1 to 4. Methods for preparing flexible foam articles utilizing the isocyanate-reactive compositions are also provided.
