Description

Reactive Red 159 is a high-performance, water-soluble azo dye belonging to the reactive dye class, designed for covalent bonding with textile fibers. This compound is valued for its excellent color fastness, brilliant red hue, and efficient application in modern dyeing processes. It is primarily used by manufacturers in the textile industry for dyeing and printing cellulosic fibers like cotton and viscose, as well as in research and development for advanced material coloration.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cotton, linen, and other cellulosic fabrics.
• Textile Printing: Used in pigment printing pastes for creating vibrant red patterns on natural fiber textiles.
• Leather Coloration: Employed in the dyeing of leather goods to achieve durable and vivid red shades.
• Paper Coloring: Suitable for specialty paper grades requiring high color intensity and stability.
• Biomaterial Staining: Potential use in laboratory settings for histological staining or as a colorimetric indicator.
• Ink Formulation: A component in the manufacture of inks for specific industrial marking or printing applications.

Quality Control

Our Reactive Red 159 is produced under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including color strength, solubility, and reactive group content. A Certificate of Analysis (COA) detailing purity, physical properties, and application performance is 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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect performance.
