Application Range and Benefits:  

   For organic or inorganic pigment surface treatment, increase the dispersability and color strength, improve the mobility and tinctorial effect.  

Usage and dosage:  

   Heat 20phr CH-15C to its melting point, then drop it slowly into 50-55℃ 1.5% glacial acetic acid water solution, stir rapidly more than half an hour to make the emulsion. Add the emulsion to the pigment，go on stirring for more than half an hour at 50℃ or above. The dosage is 1-3% of the dry weight of the inorganic pigment, 3-20% of the organic pigment. 

    For phthalocyanine or benzidine yellow pigment surface treatment, it is better to cooperate CH-15C with mono-sulfated derivative of the pigment. First mix the pigment with the derivative, then add the emulsion of CH-15C. The dosage of sulfated derivative is 2-8% of the dry weight of the pigment.
