Estimating the term…
The present invention relates to aqueous polyurethane dispersions containing amide groups that are pendant to the backbone of the polyurethane, wherein the amide groups (calculated as NH—CO—, MW43) are present in an amount of 1 to 14% by weight, based on the weight of the polyurethanes. The present invention also relates to aqueous, one-component, thermoset compositions containing the polyurethanes with amide groups in the backbone and a cross-linking component that is reactive with amide groups. Finally, the present invention relates to coatings, sealants and adhesives prepared from these aqueous, one-component, thermoset compositions.
