从India供应商批发进口Acid Black 2 — FOB条款

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.

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.
