Description

Solvent Red 41 is a synthetic organic dye belonging to the azo class, identified by CAS No. 3248-93-9. This high-purity colorant is valued for its strong, stable red hue and excellent solubility in non-polar to moderately polar organic solvents. It is primarily used by manufacturers in the plastics, coatings, and specialty ink industries who require consistent, vibrant coloration for their products. Our supply ensures reliable performance and batch-to-batch uniformity for critical industrial applications.

Application

Solvent Red 41 is a versatile colorant employed across various industrial sectors where solvent-based coloration is required.

• Plastics and Polymers: Coloring of polystyrene (PS), acrylics (PMMA), and other engineering plastics.
• Industrial Coatings and Paints: Used in solvent-borne systems for automotive refinish, industrial maintenance, and decorative coatings.
• Printing Inks: Formulation of specialty inks for flexographic, gravure, and screen printing applications.
• Wood Stains and Varnishes: Providing transparent to translucent red shades in wood treatment products.
• Waxes and Polishes: Coloration of automotive waxes, shoe polishes, and floor care products.
• Lacquers and Solvent-based Markers: A key component for producing bright, fast-drying colored films.

Quality Control

Our Solvent Red 41 is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for color strength, hue, and purity. A Certificate of Analysis (COA) detailing key parameters such as assay, solubility, and impurity profile is provided with each shipment to guarantee traceability and compliance with customer requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat sources and incompatible materials. Due to its light-sensitive nature, prolonged exposure to direct light should be avoided to maintain product integrity.
