  • Binding compositions for lignocellulosic composites and method for the preparation thereof
    Patent number: 5214081
    Abstract: Binding compositions for lignocellulosic composites comprising an aqueous emulsion containing at least one polyisocyanate and at least one water-dispersed acetovinyl resin having a glass transition temperature (Tg) lower than 5.degree. C. These compositions impart green tack cohesion to the resinate lignocellulosic material.
    Type: Grant
    Filed: August 19, 1992
    Date of Patent: May 25, 1993
    Assignee: Presidenza Del Consiglio Dei Ministri
    Inventors: Agostino Lepori, Ignazio Zavatteri, Mario Cova

  • Aqueous dispersions of fluorinated polyurethanes and their use for textile coatings
    Patent number: 5068135
    Abstract: Aqueous dispersions of fluorinated polyurethanes obtained by the reaction of an organic diisocyanate with a mixture of diols containing ionizable groups and macroglycols comprising polyols and at least 1% by weight of one or more hydroxy- and/or carboxy-capped fluoropolyethers. Said fluorinated polyurethanes are salified, to transform the ionizable groups into hydrophilic cations and/or anions, and are then dispersed in water to be used in textile coatings.
    Type: Grant
    Filed: October 12, 1990
    Date of Patent: November 26, 1991
    Assignees: Ausimont S.p.A., Larac S.p.A.
