Applications

Additives for Printing Inks
Abrasion resistant characteristics of CHEMIPEARL™

1.Particles project above the surface of the ink.

2.In the rub-off test,particles are spread on the surface of the ink.

3.Soft wax dispersion has excellent rub-off resistance *1,but gives low slide angle.
