Description

Basic Yellow 28 is a cationic, quaternary ammonium-based dye belonging to the methine class of colorants. This compound is valued for its strong affinity to polyacrylonitrile and other synthetic fibers, providing excellent color fastness and brightness. It is primarily utilized in the textile industry for dyeing and printing, as well as in the production of specialty inks and paper. Its specific properties make it a key component for manufacturers requiring vibrant and durable yellow shades.

Application

• Primary dyeing of acrylic fibers and their blends.
• Printing applications on synthetic textiles.
• Coloration of paper and specialty paper products.
• Manufacturing of inks for various industrial marking and coding.
• As a colorant for leather and synthetic leather goods.
• Potential use in biological staining for microscopy (subject to specific purity grades).

Quality Control

Our Basic Yellow 28 is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent color strength, purity, and performance. A Certificate of Analysis (COA) detailing parameters such as assay, shade, solubility, and impurity profile is provided with every shipment. We can support compliance with relevant industry and ecological standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after use to prevent absorption of atmospheric moisture, which can affect product performance.
