WATER-DISPERSIBLE POLYISOCYANATE COMPOSITION, PROCESS FOR ITS PRODUCTION, WATER-BASE CURABLE COMPOSITION AND ITS APPLICATION

Document Type and Number:

WIPO Patent Application WO/2002/032977

Kind Code:

A1

Abstract:

A water-dispersible polyisocyanate composition which comprises a hydrophobic polyisocyanate (A) and a vinyl polymer (B) bearing both a nonionic group and an isocyanate group and is characterized in that the polyisocyanate (A) can be dispersed in an aqueous medium by virtue of the vinyl polymer (B). The composition can be produced by reacting a hydrophobic polyisocyanate with a vinyl polymer (b) bearing a nonionic group and an active hydrogen containing group reactive with an isocyanate group at a molar ratio of isocyanate group to the active hydrogen containing group of 3 to 350.
