Aqueous polyurea dispersions and their use for preparing coatings with excellent hydrolytic and thermal stability

摘要

The present invention relates to aqueous dispersions of polyureas containing hydantoin groups (calculated as C3N2O2, MW 96) in an amount of 1 to 40% by weight, based on resin solids. The present invention also relates to the use of these dispersions for preparing coatings having excellent hydrolytic and thermal stability.
