NEROX® 305 carbon black pigment is a Regular Color Furnace Black (RCF) type. It offers various levels of optical density and undertone, easy dispersing with high optical density and good hold-out, excellent coloristic properties and rheology, as well as an excellent balance of properties for sharp imaging and optimum gloss. Used for printing inks, masstone coloring in pure black coatings (e.g., in automotive basecoats), for tinting in gray coatings and paints (e.g., in decoration), and for light tinting in transparence coatings (e.g., for metallic effects and wood glazing). The use of oxidized pigment in solvent borne coatings and non or weak oxidized pigment in water borne coatings is recommended. It is also useful in powder and radiation curing coatings.
