Description

Acid Red 26:1 is a synthetic azo dye lake, commonly known as Lithol Rubine BCA. This high-performance pigment is valued for its strong, bluish-red shade and excellent chemical resistance, making it a critical component for producing durable, vibrant colors. It is primarily used by manufacturers in the coatings, plastics, and printing ink industries seeking consistent, high-quality pigmentation.

Application

• Printing Inks: A key pigment for offset, gravure, and flexographic printing inks, providing excellent printability and color strength.
• Industrial Coatings: Used in automotive, coil, and general industrial paints for its durability and weather resistance.
• Plastics Coloring: Imparts a stable red color to PVC, polyolefins, and other polymers during mass coloration.
• Masterbatch Production: Serves as a concentrated colorant for creating plastic color masterbatches.
• Paper Coatings: Employed in the surface coloring and coating of specialty papers and packaging.
• Artist Colors: Used in the formulation of certain professional-grade artist paints and pigments.

Quality Control

Our Acid Red 26:1 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance. Quality is verified through comprehensive testing for key parameters including color strength, shade, particle size distribution, and chemical purity. Certificates of Analysis (COA) documenting these results are provided with every shipment to support your quality assurance protocols.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed when not in use to prevent moisture absorption, which can affect product performance.
