从India供应商批发进口Acid Red 186 Dyes — FOB条款

Acid Red 186 is a synthetic acid dye with CAS number 52677-44-8, also known in industry as Complex Pink B. Supplied by Sparrowings International from Gujarat, India, this powder-form dye has the molecular formula C20H14N4Na2O8S2 and EINECS number 258-095-1. It is classified as an acid dye primarily used for colouring leather, textiles and polyamide fibres, delivering consistent, vibrant hues in industrial applications.

The dye’s chemical structure supports strong affinity for protein and polyamide substrates, ensuring uniform penetration and colourfastness.

The powder form allows for easy handling and precise dosing in bulk production environments.
