ABSTRACT:
A self-emulsifiable polyisocyanate mixture having a hexamethylene diisocyanate monomer content of not more than 1.0% by weight and an average NCO functionality of 2.0 to 3.7 obtained by subjecting hexamethylene diisocyanate to urethanation with a branched dihydric alcohol having overall 4 to 35 carbon atoms, of which 2 to 33 carbon atoms are a total number of the carbon atoms possessed by one or more branches, a hydrophilic surfactant having one or more active hydrogen atoms capable of reacting with NCO group and 3 to 90 alkylene oxide units, an aliphatic compound having one or more active hydrogen atoms capable of reacting with NCO group and 8 or more carbon atoms and an unbranched glycol having 1 to 10 carbon atoms; uretdione-forming reaction; and isocyanurate-forming reaction. Said self-emulsifiable polyisocyanate mixture is excellent in compatibility, dispersion stability and NCO group-stability and can be combined with water or a water-soluble resin and/or an aqueous emulsion, and if necessary, an additive to provide an aqueous coating or adhesive composition excellent in heat resistance, workability, coating film appearance, weather resistance and adhesion to substrate.
