  • Polyisocyanate coating compositions cross-linkable into enhanced anti-shock coatings
    Patent number: 8318310
    Abstract: Polyisocyanate coating compositions, the polyisocyanates of which include dimer structural units (patterns) and imino-trimer structural units (patterns), are converted, via cross-linking, into useful such coatings as paints or varnishes having enhanced shock-resistant properties, notably chip-resistant properties for vehicle body parts.
    Type: Grant
    Filed: March 22, 2007
    Date of Patent: November 27, 2012
    Assignee: Perstorp France
    Inventors: Jean-Marie Bernard, Mathias Dubecq
  • Polyisocyanate composition having improved impact-proof properties
    Patent number: 8188171
    Abstract: The invention relates to the use of additived (poly)isocyanate compositions for producing coatings, especially paints or varnishes for car bodywork parts, said compositions having excellent impact-resistant properties, especially grit-resistant properties.

  • Polyisocyanate Composition Having Improved Impact-Proof Properties
    Publication number: 20080044578
    Abstract: The invention concerns a method for providing a substrate with a coating with high impact strength properties, characterised in that it consists in applying on said substrate an aqueous masked (poly)isocyanate emulsion having a droplet average size less than 10 ?m, advantageously less than 5 ?m, preferably less than 1 ?m, and in reacting it with a polyol in conditions leading to crosslinking of the (poly)isocyanate with the polyol.
