TOL & MEK Free PU Binders for Ink

PU resin (PU ink binder) is one of the important raw materials for  inks. COMENS offers two types of  TOL & MEK free PU binders: film forming and plasticizing type. The Film forming grade PU binder is used to make rotogravure reverse lamination ink, and combines with vinyle resins.  It can be dissolved with environmental friendly solvent, has very good heat-resistance, can be treated by water-boiling and retorting and meet most of the strict requirements for the high performance rotogravure reverse ink. The plasticizing grade PU binder is used to make flexo or rotogravure surface printing ink,  combines with NC resin. It is also TOL & MEK free, with high gloss and excellent alcohol solubility.
