Abstract (en)
[origin: WO2022165622A1] A water-dispersible polyisocyanate composition contains a hydrophobic polyisocyanate (A) and an acrylic polymer (B) containing an alkoxy group end-capped polyoxyalkylene group and an isocyanate group. The acrylic polymer (B) is a reaction product of an acrylic polymer (b) and a hydrophobic polyisocyanate. The acrylic polymer (b) contains a polymer (bl) and a polymer (b2). The polymer (bl) is derived from a monomer raw material containing 11 mol% or more and 35 mol% or less of an acrylic monomer (x) having an alkoxy group end-capped polyoxyalkylene group. The polymer (b2) is derived from a monomer raw material containing 2 mol% or more and less than 11 mol% of the acrylic monomer (x). The water-dispersible polyisocyanate composition provides a long pot life in the form of a two-component paint and excellent appearance of a coating film to be formed and thus can be sutibaly used for various paint applications.
