The Formula
Formulation
Stability
Solvent Black 3 is generally thermostable, stable under typical temperatures and pressures, with a melting point of 120-124 °C and heat resistance up to 300°C in specific plastic matrices. However, it demonstrates sensitivity to light and significant pH fluctuations, changing color in the presence of strong acids (purple-black to dark green-blue) and strong bases (dark blue). Optimal storage requires a cool, dry environment in tight, light-resistant containers to maintain stability.
