Ranbar Violet P6018/P6020/P6022 dioxazine violet pigment, also known as carbazole violet, pigment violet 23, this structural pigment currently has three main models: P6018, P6020 and P6022, In addition to the different hue, the processing technology, post-treatment and scope of application are also different.
Widely used in coatings, printing inks, plastics and fabric printing and dyeing and other fields; good fastness to varnish when the coating is colored, can be used in air-drying paint, automotive coating OEM and baking paint, etc., and can be matched with phthalocyanine blue Obtain a latex paint with a strong red hue;
Used for plastic coloring, heat-resistant to 280°C in polyolefin with high tinting strength (HDPE of 1/3 SD only needs a pigment concentration of 0.07%);
It is also used in original pulp coloring of polyester and PE (it can withstand 240-280℃/5-6h during the resin condensation process);
Good light and weather fastness makes it suitable for coating printing and printing ink.
