UCECOAT® 7655 is a radiation curable polyurethane dispersion which is tack-free before cure and after water evaporation. It has been developed for high end wooden furniture top-coats, both transparent and pigmented, but can also be used for other applications and substrates. This polyurethane dispersion is very reactive and exhibits very good scratch resistance. Due to the low viscosity, it can be applied by spray or curtain coater.
