Product Description of Pigment Red 2:

Pigment Red 2 is neutral red, slightly yellowish than CI Pigment Red 112, but the light fastness is 0.5-1 grade lower than that, with larger particle size and lower transparency; mainly used in offset printing and packaging inks, textile printing and dyeing and viscose fibers The original paste coloring is less used for paint coloring; the resistance to varnish, high temperature sterilization and solvent resistance is lower than that of Pigment Red 112.

Pigment Red 2 is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.

Safety Information

Stability/Shelf Life:

Stable. Incompatible with strong oxidizing agents.

Fire Hazards:

Flash point data for this chemical are not available, however it is probably combustible. (NTP, 1992)

Fire Fighting:

Fires involving this compound can be controlled using a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)

Nonfire Spill Response:

SMALL SPILLS AND LEAKAGE: If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then dampen the solid spill material with toluene, then transfer the dampened material to a suitable container. Use absorbent paper dampened with toluene to pick up any remaining material. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal. Solvent-wash all contaminated surfaces with toluene followed by washing with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned. STORAGE PRECAUTIONS: You should store this material in a refrigerator. (NTP, 1992)

Personal Protective Equipment:

RECOMMENDED RESPIRATOR: Where the neat test chemical is weighed and diluted, wear a NIOSH-approved half face respirator equipped with an organic vapor/acid gas cartridge (specific for organic vapors, HCl, acid gas and SO2) with a dust/mist filter. (NTP, 1992)
