CHEMIPEARL(development article)

Polyolefin-based Aqueous Dispersion

CHEMIPEARL™, which is made of fine particles of polyolefin, uses Mitsui Chemicals’ unique technology and is an environmentally friendly aqueous dispersion that does not use emulsifying agents or organic solvents (except for some grades and Products in Development).

Abrasion resistant Improved slip properties Anti-blocking agent Superior application properties Outstanding heat-sealing properties Hygienic qualities

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.
