CN823 is a new acrylic oligomer that reportedly can improve adhesion of UV/EB ink formulations. When combined with an oligomer imparting good pigment wetting and lithographic ink performance, CN823 can enhance the level of adhesion to non-porous substrates such as plastics and metals.

CN823 is reportedly suitable for use in all ink formulations. It has particular use in offset and offset lithographic inks because of the hydrophobic nature of the oligomer backbone. The oligomer also has improved compatibility with the acrylate monomers and oligomers typically favored for use in lithographic inks.
