| Use | This pigment is a newly developed new structural pigment variety, having blue-red color and stronger blue light than pigment red 170 and pigment red 210. Its application performance is not as good as pigment red 170, such as low light resistance 0.5-1 grade, sensitive to varnish, sterilization treatment, other properties are similar (such as tinting, gloss and transparency). Mainly used in coating and solvent ink and water-based ink, fabric printing and dyeing. The pigment varieties give neutral red, there are two kinds of crystal type products; Transparent blue red light fastness is grade 6, non-transparent light fastness is grade 7, high hiding power, more stable to solvents; Novoperm Red F2RK 70 specific surface area of 23 m2/g; Mainly used in coatings, with molybdenum chrome orange, quinacridone color matching; Transparent recommended |
