Acid Black 2, supplied by Sparrowings International from Gujarat, India, is a powder-form acid dye used primarily in ink, leather, paper, and textile dyestuff applications. Identified by CAS number 8005-03-6 and EINECS number 616-852-7, this dye is also known as Acid Nigrosine Black, a common nomenclature in the industry for black acid dyes with high tinctorial strength.
The dye’s chemical structure is designed for strong affinity to cellulosic and protein-based fibres, as well as non-fibrous substrates like paper and leather. Acid Nigrosine dyes like Acid Black 2 are known for their deep black shades and are often used where high colour intensity and uniformity are required. The powder form allows for easy dispersion in water, making it suitable for both exhaust and continuous dyeing processes.
Sparrowings International positions Acid Black 2 for buyers in the ink, leather, and textile sectors, where consistent black colouration is critical. The dye is particularly valued in applications such as leather finishing, where even colour penetration and resistance to crocking are essential. Importers should specify their intended use to ensure the dye’s properties align with their production needs, as acid dyes can vary in performance based on substrate and process conditions.

Before ordering Acid Black 2, verify its suitability for your specific application by requesting a sample for lab testing.

Ensure the dye’s chemical identity matches your requirements by cross-referencing the CAS and EINECS numbers provided by Sparrowings International.
Clarify logistics details, including lead time, which may depend on order volume and the supplier’s production schedule. Agree on Incoterms, such as FOB or CIF, to define responsibilities for shipping, insurance, and import duties.

Upon receipt, inspect the dye for consistent powder form, absence of clumping, and uniform black colour.

For leather applications, conduct a crocking test to ensure the dye meets your quality standards. If the dye is intended for regulated industries, confirm adherence to local chemical safety and environmental regulations.
