Copeblack 450

Copeblack 450 by Birla Carbon is a carbon black. It exhibits optimum performance in jet-ness, undertone, tint, gloss, stability, and rheology. Provides better pre-wetting of black, removal of the bulk of entrained air, initiation of the dispersion process, more uniform initial viscosities which provide for optimum shearing, faster and more complete dispersion on the mill, less “puffiness” of mill paste due to entrained air and reduced degradation of vehicles oversensitive to oxidation and polymerization. Offers UV protection. Copeblack 450 by Birla Carbon is used in medium color applications in low rub-off news ink.
