UV Curing behavior and physical properties of waterborne UV-curable polycarbonate-based polyurethane dispersion

摘要

Of the various classes of waterborne UV curable systems, UV dispersions are probably most useful. They are prepared by incorporating dispersing groups, such as hydrophilic or ionic groups, into the polymer backbone. Dispersions tend to provide a better hardness-elasticity balance, adhesion strength and chemical resistance. In addition, a tack-free coating is achieved after only water drying.
