CHARACTERISTICS:

1.

Provides excellent mechanical stability and chemical stability with low foaming, also good compatibility and dispersability to pigment.

2.

Coating color properties are excellent:

 
  • (1) Provides excellent workability due to its good stability and fluidity.

  • (2) Suitable for the high speed blade coater requiring excellent fluidity and mechanical stability under high shear.

  • (3) Also suitable for the air knife coater due to its low foaming

3.

Coated paper manufactured by using NANTEX®-251 provides excellent picking resistance and excellent printability, especially in blister resistance and ink set properties.

4.

NANTEX® -257AX4 can be used in sole binder color system for coated paper coating due to its strong binder force.
