  • MODIFIED POLYURETHANES
    Publication number: 20140296428
    Abstract: The present invention relates to isocyanate functional prepolymers, aqueous polyurethane dispersions produced from the prepolymers and various uses of such dispersions. The prepolymers are prepared by reacting a diisocyanate, a dihydroxy compound having a number average molecular weight of from about 700 to about 16,000, and a trihydroxy component of the formula: R—(OH)3 where R is a saturated straight chain or branched chain aliphatic group of from 2 to 8 carbon atoms. The invention also relates to polyurethane dispersions prepared from the prepolymers and to various uses of the resultant dispersions.

  • Polyurethane dispersion (PUD) with improved isopropanol resistance, flexibility and softness
    Publication number: 20060149020
    Abstract: Isocyanate-functional polyurethane prepolymers and aqueous dispersions therefrom which are useful for the production of flat materials having excellent resistance to alcoholic solvents are described. The prepolymers are prepared by reacting A) an isocyanate selected from the group consisting of i) an aliphatic and/or a cycloaliphatic isocyanate; and ii) a mixture of an aromatic isocyanate and an aliphatic and/or a cycloaliphatic isocyanate; and B) a polyester diol having a number average molecular weight of 800 to 4,000 and a polyether triol having a number average molecular weight of 200 to 3,000.
