ABSTRACT:
A NCO-free, free radical-curable polyurethane coating composition which is particularly suitable for application on heat sensitive substrate is disclosed. The coating contains an allylether-capped isocyanate prepolymer and at least one additional isocyanate prepolymer which is capped with a hydroxyalklyl(meth)acrylate. The composition of the invention yields coatings having good dry time and hardness. An additional embodiment relates to aqueous dispersions of the composition of the invention and to films made therefrom.
