  • AQUEOUS DISPERSIONS OF CATIONIC FILM-FORMING POLYURETHANES
    Publication number: 20160355632
    Abstract: Stable aqueous dispersions of film-forming cationic polyurethanes are prepared by extending with water a cationic prepolymer obtained from aliphatic diisocyanates, aliphatic tertiary amines having two hydroxyl groups that react with —NCO groups, linear polyols and methanesulfonic acid.
    Type: Application
    Filed: August 19, 2016
    Publication date: December 8, 2016
    Applicant: LAMBERTI SPA
    Inventors: Vito ALANZO, Gabriele COSTA, Dario CONTI, Giuseppe LI BASSI
  • Water dispersible polyisocyanate compositions
    Patent number: 8470444
    Abstract: Non aqueous water dispersible compositions comprising: I) polyisocyanates, which are made hydrophilic by reaction with a 1,3- or 1,2-nonionic diol containing one alkoxy-terminated polyoxyethylene and/or polyoxypropylene chain, II) one or more ethoxylated alcohol phosphates having at least one phosphoric group in acid form, and optionally III) a water miscible organic solvent, the compositions being useful as crosslinker for polyurethane aqueous dispersions.
    Type: Grant
