8400 Series Screen Ink is a polyester solvent-based/conventional screen ink which meets the requirements of various industrial and specialty print applications including, the insert mold decorating (IMD) process. The dried ink film exhibits good gloss and flexibility for forming, post-form trimming, resistance to wash out during the molding process, and adhesion to polycarbonate injection mold resin. 8400 Series ink is for second surface printing on polycarbonate, polycarbonate blend, or pre-treated polyester films which will be formed then molded in the insert mold decorating process. The addition of NB72 Catalyst or NB80 Adhesion Promoter is necessary for in-mold decorating applications..
