Usage
and dosage:
Mix
300phr Phthalocyanine Green pigment presscake (about 35% solid
content) with 50-200phr CH-16A, heat the mixture to the melting
point of CH-16A, then keep stirring at 90-100¡æ
for 4-8 hours. Add 50-200phr 20%NaOH to make the mixture to be
basic, then filtrate, wash and dry the presscake to get the
