Pigment Red 81

Hangzhou Origo Chemical Co.,Ltd offers the pigment red 81 at best price across China. Pigment Red 81 affords a very clean red shade that no other pigment has. It is a rhodamine bluish red pigment and is similar in shade to other pigment of this family. However, the pigment red 147 still has quite a difference and the shades are not even remotely as clean. Pigment Red 81 lacks fastness to polar solvents, such as alcohols, ketones and esters but it does have a strong color strength. This commonly darkens noticeably as it is exposed to light. Red 81 can be found being popularly used in inks, plastics, textiles. It is slightly soluble in water and when dry, looks like a dark pink powder. This organic pigment is known to react with mineral-based and clay-based absorbents. It is also recommended for textile printing, offset inks, water-based, solvent-based, and UV inks. Origo Chem is a leading supplier and manufacturer of the pigment red 81 in China and worldwide. Our featured product goes through rigorous quality controlling phase to ensure unmatchable quality, performance and safety.
