ABSTRACT:
A formulation for a resilient gasket coating which is curable by ultraviolet radiation without emitting fumes into the surrounding environment. Different portions of the coating are cured by successive exposure to two different wavelengths of ultraviolet radiation during a continuous in-line process. The first wavelength cures an inner portion of the coating and bonds the coating to the substrate. The second wavelength cures a coating surface. The formulation permits ultraviolet curing of thicker pigmented coatings than have been previously known.
