PIGMENT YELLOW 83/ HP YELLOW 1680

What Is PY83 / HP YELLOW 1680

Pigment Yellow 83 (PY83) is a disazo condensation organic pigment known for its brilliant greenish-yellow shade and high molecular stability. Chemically classified as a disazo yellow, it provides superior heat resistance and migration fastness compared to standard monoazo yellows. In the industrial coatings market, PY83 occupies a premium position where long-term durability and color retention under harsh environmental exposure are required, making it a preferred choice for high-performance liquid and powder coating systems.

Why Choose HP YELLOW 1680

HP YELLOW 1680 is specifically engineered for industrial coatings and paints that must withstand prolonged outdoor exposure, chemical washdowns, or high-temperature curing cycles. Its perfect fastness properties—including lightfastness, weather resistance, and solvent bleed resistance—prevent color fade and chalk formation on equipment, machinery, and architectural metal panels. The high color strength of this grade reduces the pigment loading needed to achieve full chroma, which lowers formulation cost and maintains the coating’s mechanical integrity. In industrial environments, this translates to fewer repainting cycles, consistent batch-to-batch color, and reliable performance on substrates like coils, heavy-duty machinery, and transportation equipment where coating failure is costly.

Key Features

• Its disazo condensation structure delivers exceptional lightfastness and weather resistance, ensuring industrial coatings retain their tint strength and gloss after years of UV exposure.
• The pigment exhibits very low migration and blooming in solvent-based and powder coating systems, which prevents staining of adjacent layers or color bleeding into the coating film.
• HP YELLOW 1680 maintains thermal stability at temperatures common to powder coating curing ovens, allowing formulators to achieve deep yellow shades without thermal degradation.
• Its high hiding power and inherent color strength let industrial paint formulations use less pigment to reach target opacity, improving cost efficiency without sacrificing film performance.
• The material resists acid, alkali, and chemical attacks typical in industrial environments, so coated parts can withstand aggressive cleaning agents and atmospheric pollutants without discoloration.

C.I.NO.: PY83

Advantage:  Perfect fastness, high color strength

Main Application Recommended: Industrial Coatings & Paints

Product Description – PY83

HP YELLOW 1680 (Pigment Yellow 83) transparency type and hemi-trans type, yellow HR02
It possesses excellent fastness properties, which make it almost universally applicable. It provides a reddish yellow hue, which is considerably more reddish than that of P.Y.13 and at the same time very strong. It is the standard pigment within the reddish yellow range. It shows good to very good resistance to most solvents which are typically found in application media. It shows excellent lightfastness, even in methylmethacrylate or unsaturated polyester cast resins. The pigment does not affect the hardening of the latter. It is also used to an appreciable extent in plastics. Because of its good solvent resistance, migration is no problem in plasticized PVC even at low pigment levels; it does not bleed or bloom. HP YELLOW 1680 (Pigment Yellow 83) is characterized by its remarkable versatility and strong performance in various applications. This pigment ensures consistent coloration and stability across a range of mediums, reinforcing its status as a preferred choice for manufacturers. Furthermore, its compatibility with different formulations enhances its usability, making it an essential component in industries such as coatings, plastics, and inks. Its superior fastness properties not only ensure longevity but also maintain the integrity of the final product, even under challenging conditions.

Recommended Application：

Coatings: architectural coatings, coil coatings, industrial paints, powder coatings,
plastics: PVC, rubber, PS, PP, PE, PU,
Printing inks: offset inks, water-based inks, solvent inks, UV inks, printing pastes

Technical Data:

• Light fastness: Light fastness rating is assessed on 1 to 8 Blue Wool scale where 1 = ‘Poor’ and 8 = ‘Excellent’.
• Heat Stability : Heat stability values given indicate the maximum temperature at which the pigment can be stoved for 10 min. on the full shade and in reductions without undergoing any significant change in shade.
• Oil absorption: The oil absorption is determined on the basis of EN ISO 787-5 and given in g linseed oil per 100 gm. pigment.
• Solvent bleeding: The bleeding in solvents is tested using the powder grades and the visual rating given on 1 to 5 Grey scale
  where 1 = ‘Heavy bleeding’ and 5 = ‘No bleeding”
