Boltorn™ H2004 is a liquid fatty acid modified dendritic polymer with 6 terminal hydroxyl groups. This dendritic polyol not only offers the general advantages of polyols in cationic systems like improved flexibility and reactivity, but also further improves the chemical resistance and rheological behavior of flexographic inks while maintaining high curing speed. The Newtonian behavior of printing inks containing Boltorn™ H2004 improves ink transfer at high speeds.
