Solvent Red 49

Solvent Red 49: Overview & Applications

Solvent Red 49 is a high-performance, oil-soluble azo dye renowned for its vibrant orange-red hue and exceptional stability in non-polar environments. With the chemical formula C₂₄H₂₀N₄O₂, this dye is widely utilized in industries requiring intense coloration and resistance to heat, light, and solvents. Its versatility and reliability make it a preferred choice for applications where both aesthetic appeal and durability are critical.

Key Applications

1. Plastics Industry:
   Solvent Red 49 is extensively used for coloring thermoplastic materials such as PVC, polystyrene (PS), and polycarbonate (PC). It is particularly favored for products exposed to high-temperature processing (e.g., injection molding or extrusion), as it maintains color integrity without fading or migration. Common end uses include packaging films, household appliances, and automotive components.

2. Inks & Coatings:
   The dye’s excellent solubility in organic solvents (e.g., toluene, acetone, and ethyl acetate) makes it ideal for solvent-based inks and industrial coatings. It delivers bright, long-lasting shades for printing on plastics, metals, and synthetic fabrics, ensuring sharpness in logos, labels, and decorative finishes.

3. Waxes & Specialty Products:
   In candle manufacturing and wax-based polishes, Solvent Red 49 provides uniform coloration with minimal bleeding, even in molten states. It is also employed in wood stains and leather finishes to achieve consistent, fade-resistant results.
