NeoRad™ P-50 is recommended as a pigment grinding vehicle for all types of energy curable (ultraviolet light (UV) or electron beam (EB)) printing inks. This polyester acrylate can be used in combination with a wide range of monomers to prepare pigment concentrates using reduced amounts of dispersing agent.The final energy curable printing ink is obtained when the pigment concentrate is combined with the technical varnish to get the desired set of properties.
