For research and development scientists, product developers, and technical procurement managers, a deep understanding of a pigment's technical specifications is crucial for successful formulation. Pigment Red 177 (CAS 4051-63-2) is an organic pigment renowned for its anthraquinone chemistry, which imparts a unique set of high-performance characteristics. As a dedicated supplier of Pigment Red 177, NINGBO INNO PHARMCHEM CO.,LTD. provides detailed technical insights to support your material selection process.

This article aims to provide an in-depth look at the technical properties of Pigment Red 177, highlighting why it is a preferred choice for demanding applications where standard pigments may not suffice.

Chemical Identity and Structure

Pigment Red 177 belongs to the anthraquinone class of organic pigments. Its chemical structure is the basis for its excellent stability and performance. The key identifiers are:

  • Chemical Name: 4,4'-Diamino-[1,1'-bianthracene]-9,9',10,10'-tetraone
  • CAS Number: 4051-63-2
  • C.I. Name: Pigment Red 177
  • C.I. Structure Number: 65300
  • Molecular Formula: C28H16N2O4
  • Molecular Weight: 444.44 g/mol

The complex, conjugated aromatic structure of anthraquinone derivatives is responsible for their inherent stability, including resistance to heat and light. Understanding these fundamentals helps R&D scientists to predict performance in various matrixes.

Key Performance Parameters for Formulators

When considering how to buy Pigment Red 177, formulators look at these critical performance metrics:

  • Light Fastness: Rated typically at 7-8 on a scale of 8, Pigment Red 177 offers outstanding resistance to fading from UV light exposure. This is critical for exterior applications and products requiring long-term color stability.
  • Heat Resistance: In plastic processing, heat stability is paramount. Pigment Red 177 can withstand temperatures of up to 300°C in certain polymers like HDPE without significant deformation, though performance can vary with concentration and polymer type. This makes it suitable for masterbatch and compounding.
  • Transparency: Its high degree of transparency allows for the development of brilliant, clean shades and is advantageous in applications requiring depth of color or specific optical effects.
  • Chemical Resistance: It demonstrates good resistance to acids and alkalis (typically rated 5/5), ensuring color integrity in chemically demanding environments.
  • Tinting Strength: High tinting strength allows for efficient coloration, meaning less pigment is required to achieve the desired color depth, contributing to cost-effectiveness for manufacturers.
  • Halogen-Free: For applications where halogen content is a concern (e.g., certain electronics or safety regulations), Pigment Red 177 is typically halogen-free, providing an advantage.

Applications Benefiting from Technical Advantages

The technical superiority of Pigment Red 177 makes it ideal for:

  • Automotive Coatings: Its exceptional weatherability and vibrant hue are essential for OEM and refinish paints.
  • High-End Plastics: Applications requiring high heat stability and excellent lightfastness, such as automotive interior components, consumer electronics, and specialized packaging.
  • Specialty Inks: High-transparency inks for packaging, security printing, or decorative finishes.
