从India供应商批发进口Acid Black 58 — FOB条款

Acid Black 58, also known by its CAS number 12218-94-9 or the alternative name Neutral Grey BL, is an acid dye with the molecular formula C19H17N3O5S. Produced by Sparrowings International, this dye is specifically formulated for use in leather and textile dyestuffs, as well as polyamide materials. The product is supplied in powder form, ensuring ease of handling and application in industrial settings.

As an acid dye, it exhibits strong affinity for protein-based fibres and polyamide substrates, delivering consistent colouration with good penetration. The dye’s chemical structure is optimised for stability under typical dyeing conditions, with standard light and wash fastness properties expected for this class. Its appearance as a fine powder allows for uniform dispersion in dye baths.

This product is particularly suited for leather finishers and textile manufacturers seeking reliable black or grey shades. Buyers should confirm the dye’s performance under their specific pH and temperature conditions, as these factors influence colour uptake and fastness. Sparrowings International, based in Gujarat, offers this dye under its own brand name, with packaging and logistics details available upon request.
