Product Description Product Name  Hermcol® Red 4BP (PR 57：1) C.I. No  Pigment Red 57：1 CAS No  5281-04-9 EINECS No.  226-109-5 Molecular Formula  C18H12CaN2O6S Pigment Class  Mono azo Features Hermcol® Red 4BP is a bluish red pigment and has excellent dispersibility. Hermcol® Red 4BP is a yellow shade Calcium laked BONS Red pigment. It exhibits excellent coloristical properties and dispersibility, as well as low viscosity at high pigment concentration in lithographic inks. The shade meets the requirements of process colour magenta. Hermcol® Red 4BP is the most blue among the azo lake pigments and it’s cost effective. Hermcol® Red 4BP is not suitable for use in concentrations below approximately 0.03% and only use in deep color. Hermcol® Red 4BP is heat stable up to about 220°C-240°C/5min in polyolefin and nose dive when concentration below 0.1%. Application Hermcol® Red 4BP is a calcium salt of monoazo lake red pigment, with high luster, low viscosity, having good performance in solvent based inks. Its main use is PA inks and NC inks, suggested for water based inks and Toluene-base Inks. It is also recommended for plastics, PP, PE, PVC, PS, PC, PET, ABS, polyurethane, fiber, rubber, powder coatings, also suitable for industrial paints. Package 25kgs or 20kgs per paper bag/drum/carton. *Customized packaging available on request.
