Epoxy modified polyurethane, UV-curing coat and preparation method thereof

The present invention discloses a polyurethane and an epoxy-modified UV-curable coatings and their method of preparation. The UV-curable coating, comprising a binder, a photoinitiator, a diluent, said body comprising a polyurethane resin, an epoxy-modified, said photoinitiator is a cationic photoinitiator. After disclosure of the present invention, UV curable coating is cured under conventional conditions, good mechanical properties of the resulting coating, combined with the strong base. Deformation occurs when the substrate, the coating does not produce problems such as falling off.
