POLYURETHANE DISPERSION AND POLYURETHANE LAMINATE |
摘要 |
A polyurethane dispersion is a polyurethane dispersion in which polyurethane resin produced by reaction of an isocyanate group-terminated prepolymer with a chain extender is dispersed in water. The isocyanate group-terminated prepolymer is produced by at least allowing a polyisocyanate component containing xylylene diisocyanate and/or hydrogenated xylylene diisocyanate to react with a polyol component containing diol having 2 to 6 carbon atoms, a low-molecular-weight polyol having a functionality of three or more, and an active hydrogen group-containing compound containing a hydrophilic group. The chain extender contains an alkoxysilyl compound having a primary amino group, or a primary amino group and a secondary amino group, and the molar ratio of the hydroxyl group in the low-molecular-weight polyol having a functionality of three or more is less than 25% relative to a total mol 100% of the hydroxyl group in the polyol component. |
