摘要： A one-component-type composition for a polyurethane elastomer, comprising as a main component a polyurethane precursor containing a polyisocyanate component, and a compound having active hydrogen groups. The polyisocyanate component contains a polyisocyanate having at least a urethodione group (particularly urethodione and isocyanurate groups), and the compound (polyol or the like) having active hydrogen groups contains at least two active hydrogen groups in its molecule and has a molecular weight of 18 to 20000. The polyurethane precursor is obtained by reacting the polyisocyanate component and the compound having active hydrogen groups under the condition that the equivalent ratio of the active hydrogen group in the compound having active hydrogen groups to the isocyanate group in the polyisocyanate component exceeds 1.0. The equivalent ratio of the urethodione group to the active hydrogen group in the polyurethane precursor is from 0.25 to 1.0. The one-component-type composition for a polyurethane elastomer has storage stability comparable to that of thermoplastic elastomers, can be handled with ease, and does not pollute working environment. The composition is useful for preparaing elastomers which have physical properties equal to those of two-component-type elastomers.

摘要： 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.
