Solvent Red 207, a prominent member of the anthraquinone dye family, plays a crucial role in various industrial coloring applications. Its unique chemical structure, coupled with exceptional performance characteristics, makes it a sought-after ingredient for manufacturers aiming for high-quality and durable color solutions. This article delves into the chemical properties of Solvent Red 207 and explores its extensive industrial uses.

Chemical Foundation of Solvent Red 207

The chemical name for Solvent Red 207 is typically derived from its anthraquinone backbone, featuring amine substitutions that enhance its solubility in organic solvents. Its molecular formula is often cited as C28H22N2O2, with a molecular weight around 418.49 g/mol. The CAS number, 10114-49-5, serves as a unique identifier for this compound. As a solvent dye, it is characterized by its ability to dissolve completely in organic media rather than water, which dictates its primary application areas. The specific arrangement of its chromophores and auxochromes within the molecule is responsible for its distinctive transparent blue-red shade and its stability.

Key Performance Properties

The industrial value of Solvent Red 207 is significantly attributed to its performance attributes:

  • Heat Resistance: One of its most critical features is its high thermal stability, often rated to withstand temperatures up to 300°C. This allows it to be incorporated into polymers that require high processing temperatures without undergoing thermal degradation or color alteration.
  • Light Fastness: Solvent Red 207 exhibits excellent light fastness, typically rated at grade 7 or higher on a scale where 8 is the best. This ensures that colors remain vibrant and resist fading when exposed to sunlight or UV radiation over extended periods.
  • Solubility: It readily dissolves in a range of organic solvents such as acetone, methylbenzene, and dichloromethane, which is fundamental to its application in solvent-based systems.
  • Transparency: Unlike opaque pigments, Solvent Red 207 provides a transparent coloration, ideal for applications where clarity and depth of color are desired.
  • Tinting Strength: The dye possesses high tinting strength, meaning a small amount can impart significant color, contributing to cost-effectiveness in formulations.

Industrial Applications: Where Solvent Red 207 Excels

The robust properties of Solvent Red 207 make it an indispensable colorant in several key industries:

  • Plastics: It is extensively used for coloring various thermoplastic resins including Polystyrene (PS), ABS, PMMA, Polycarbonate (PC), and PET. Its heat stability is particularly beneficial for engineering plastics used in automotive components, electronics, and consumer goods.
  • Printing Inks: Formulators utilize Solvent Red 207 to create vibrant, high-performance inks for applications like gravure, flexographic, and screen printing, where solvent solubility and color permanence are essential.
  • Coatings: It can be incorporated into solvent-based coatings to achieve transparent, rich red hues with good weatherability for various industrial and decorative finishes.
  • Fiber Spinning: For polyester and polyamide fibers, Solvent Red 207 offers consistent coloration during the spinning process, providing durable and appealing shades.
