Title (EN) WATER-DISPERSIBLE POLYISOCYANATE COMPOSITION, PROCESS FOR ITS PRODUCTION, WATER-BASE CURABLE COMPOSITION AND ITS APPLICATION
(FR) COMPOSITION DE POLYISOCYANATE DISPERSABLE DANS L"EAU, SON PROCEDE DE PRODUCTION, COMPOSITION DURCISSABLE A BASE D"EAU ET SON APPLICATION
Abstract: front page image
(EN)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.
(FR)L"invention concerne une composition de polyisocyanate dispersable dans l"eau comprenant un polyisocyanate hydrophobe (A) et un polymère vinylique (B) renfermant chacun un groupe non ionique et un groupe isocyanate, caractérisée en ce que le polyisocyanate (A) peut être dispersé dans un milieu aqueux à l"aide du polymère vinylique (B). Cette composition peut être produite en faisant réagir un polyisocyanate hydrophobe avec un polymère vinylique (b) renfermant un groupe non ionique et un groupe contenant de l"hydrogène actif réagissant avec un groupe isocyanate, avec un rapport molaire du groupe isocyanate au groupe contenant de l"hydrogène actif compris entre 3 et 350.
