Description

Reactive Red 24 is a high-purity, reactive azo dye designed for demanding industrial coloration processes. Its primary value lies in its ability to form a covalent bond with cellulosic fibers, resulting in exceptional wash and light fastness properties. This product is essential for manufacturers in the textile industry seeking vibrant, durable red shades on cotton, viscose, and other natural fabrics.

Application

• Textile Dyeing: Primary application for exhaust and continuous dyeing of cellulosic fibers like cotton, linen, and rayon.
• Fabric Printing: Used in printing pastes for creating sharp, colorfast red patterns on woven and knitted textiles.
• Leather Coloring: Imparts durable red coloration to finished leather goods.
• Paper Staining: Employed for coloring specialty papers where high color strength is required.
• Research & Development: Serves as a reference standard or intermediate in chemical synthesis and dye research laboratories.

Quality Control

Our Reactive Red 24 is manufactured 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 fixation properties. A comprehensive Certificate of Analysis (COA) detailing purity, shade, and physical specifications is provided with every shipment to guarantee it meets your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The product is hygroscopic (moisture-sensitive); ensure the original container is resealed tightly after use to prevent moisture absorption and caking.
