Polyurethane ink resin
Polyurethane Resin for Inks
PU resin (PU ink binder) is one of the important components in printing ink formulation . Comens supply two types of TOL & MEK free PU resins: film forming grade and plasticizer type.
The Film forming grade PU resin is used to make gravure reverse lamination ink, and combines with vinyle resins. It can be dissolved with environmental friendly solvent; has very good heat-resistance and can be treated by water-boiling and retorting; and meet most of the strict requirements for the high performance ink..
The plasticizer grade PU resin is used to make flexo surface printing ink, and combines with NC resin. It is also TOL & MEK free, with high gloss and good alcohol solubility.
