POLYISOCYANATE MIXTURE

摘要

A polyisocyanate mixture which is emulsifiable in water comprising; (i) An isocyanate functional oligomer, which is the reaction product of; (a) a polyisocyanate having tertiary isocyanate groups, and (b) a hydrophilic polyether having a group which will react with tertiary isocyanate groups, and (ii) a polyisocyanate having tertiary isocyanate groups. The polyisocyanate mixtures can be used with suitable film-forming polymers to make aqueous coating compositions.
