Description
Pigment Red 2 (CAS 6041-94-7) is a monoazo organic pigment registered under EC 227-930-1 with the molecular formula C23H15Cl2N3O2. It is commercially identified by the Colour Index designation C.I. 12310 and traded under names including Fast Red F 2R and Confastred 2R. No E-code designation applies to this substance.
In printing inks, Pigment Red 2 delivers strong tinting strength in solvent-based and oil-based systems by anchoring to substrate surfaces through adsorption, resisting bleed and migration. In plastics and coatings, it provides heat-stable coloration at processing temperatures typical of polyolefin compounding, while its surface wetting characteristics support uniform dispersion in resin matrices.
Pigment Red 2 is supplied as a dry powder in fibre drums or multiwall bags, with grades available for ink, coating, and polymer applications. It falls under REACH regulation and requires an up-to-date Safety Data Sheet for EU procurement. Buyers should confirm grade-specific purity and dispersibility specifications with the supplier prior to ordering.
