About Auramine Dyes

Auramine Dyes crystallize as yellow needles when it is pure. Both ethanol and water readily dissolve it. They may be used to dye acrylic fibres, silk, cotton fibre, leather, paper, hemp, and viscose. These dyes can also be used to dye hemp, leather, and paper. Apart from these, our provided Auramine Dyes can be used to dye cotton that has been colored with a tannin mordant, as well as to make color lakes and be used in inks.

Wide Range of Industrial Uses

Auramine Dyes are extensively used across multiple industries, including textiles, papermaking, leather, and biological staining applications. Thanks to their vivid yellow color and high degree of solubility, these dyes deliver consistent, reliable results on various substrates, making them highly valued by manufacturers and researchers alike.

Stability and Storage Information

Auramine Dyes offer a shelf life of up to 2 years when stored in a cool, dry, and well-ventilated area. Their stability under normal conditions, coupled with packaging in HDPE drums or bags, ensures both the integrity and safety of the product during extended storage and transport.

Safety and Handling Precautions

While Auramine Dyes are highly effective, they are also classified as hazardous and poisonous. It is essential to handle the powder with care, wearing appropriate protective equipment, and to avoid ingestion or inhalation. Ensure storage away from strong oxidizing agents to maintain safety and product quality.

FAQs of Auramine Dyes:

Q: How are Auramine Dyes typically applied in the textile and paper industries?

A: Auramine Dyes, due to their basic cationic nature, are primarily used for dyeing acrylic fibers, paper, and leather.
