Product Description
Product name: Pigment Red 168
Alternate Names: C.I.Pigment Red 168, C.I.59300, CAS 4378-61-4, Indanthren Scarlet GO, Organic pigment red 168, or 4,10-Dibromodibenzo(def,mno)chrysene-6,12-dione
C.I. Pigment Red 168 is a type of organic pigment red. It shows good compatibility in solvent systems, with a density of 1.35g/cm³, oil absorption ≤50ml/100g, pH 6.5-7.5, and heat resistance up to 180°C. Although the adhesion strength may be slightly insufficient in some drying systems, its solubility in tetralin and xylene, as well as its slight solubility in hot chloroform and o-chlorophenol, enable it to maintain stable performance in a variety of application scenarios.
