Pigment Black 30 (PBk30) is a chrome-iron-nickel spinel inorganic pigment with a bluish-black tone; unlike carbon black (organic, soot-based), PBk30 is an oxide spinel that offers superior heat and weather stability and does not bleed or migrate in many high-temperature/resin systems.
Use high-shear pre-dispersion or a concentrated masterbatch to avoid agglomerates; consider surface-active dispersants compatible with your resin system and perform lab-scale dispersion trials to optimize pigment loading and gloss influence.
PBk30 has a bluish undertone and high tinting strength; small additions can shift shade—run small batch trials to dial in final shade and opacity, especially when blending with other blacks or blue-tinted pigments.
