Application
Range and Benefits:
Azo
pigment (especially those for solvent-type coating and ink)
surface treatment. Increase the dispersability and the
solvent-resistance, decrease the viscosity, increase the color
strength, and improve the tinctorial effect.
Usage
and dosage:
Glacial
acetic acid is dissolved in water to prepare the solution, which
is to be added into the system before or during or after the
coupling reaction(before the filtration), adjust the PH to more
than 10 so that CH-8 can separate out and adsorb on the pigment
surface, then keep at 90¡æ
for more than half an hour to finish the surface treatment.
The
dosage is decided according to the pigment specific area, usual
dosage is 2-5% based on the dry weight of the pigment. You may use
higher dosage (10% for example) to treat the pigment, then mix the
treated pigment with the non-treated pigment at the proportion of
1£º4-5.
Remarks:¡¡
CH-M8, CH-8A and CH-8B has
similar properties and usage with CH-8, yet, the price is lower.
