Description

Solvent Red 207 is a high-performance, oil-soluble synthetic dye belonging to the anthraquinone class. It is valued for its excellent color strength, thermal stability, and solubility in a wide range of non-polar organic media, making it a critical component for demanding coloration applications. This product is essential for manufacturers in the plastics, coatings, and specialty ink industries seeking vibrant, durable red hues.

Application

• Plastics Coloring: Primary application for coloring a variety of polymers, including polystyrene (PS), polycarbonate (PC), and ABS, where high-temperature processing stability is required.
• Industrial Coatings and Paints: Used in solvent-based systems for automotive, industrial maintenance, and decorative coatings to provide intense, weather-resistant red colors.
• Specialty Inks: Formulation of high-performance printing inks, including for plastics and metal decoration, due to its excellent solubility and color purity.
• Synthetic Fibers: Mass coloration (dope dyeing) of synthetic fibers such as polypropylene to achieve lightfast and wash-fast colors.
• Waxes and Polishes: Coloring of candles, wax polishes, and related hydrocarbon-based products.
• Wood Stains and Varnishes: Imparting transparent, penetrating red shades in oil-based wood treatment products.
• Lubricants and Greases: Used for identification and branding purposes in specialized industrial lubricants.
