从India供应商批发进口Acid Yellow 11 — FOB条款

Acid Yellow 11, also known as Acid Yellow G, is a synthetic organic dye with the CAS number 6359-82-6 and the molecular formula C16H13N4NaO4S. This powder-form product originates from Gujarat, India, and is classified as an acid dye primarily used for colouring leather, paper, textiles, paint, and polyamide materials. Its sodium salt structure ensures strong solubility in water, making it suitable for industrial dyeing processes where vibrant yellow shades are required.

The dye belongs to the acid dye class, which typically binds to protein-based fibres such as wool, silk, and nylon through ionic interactions. Standard acid dyes like this one exhibit good lightfastness and washfastness when applied under controlled pH conditions, usually between 2 and 6. The powder form allows for precise dosing in manufacturing, and its chemical stability under typical storage conditions ensures consistent colour performance in end applications.

Textile mills, leather tanneries, and paper manufacturers commonly source Acid Yellow 11 for bulk production runs. Buyers in these sectors prioritise dyes with low heavy metal content and consistent batch-to-batch colour strength, which are verified through spectrophotometric analysis. For import, confirm compatibility with your substrate and process parameters, as application methods may vary by material. The product is typically shipped in sealed bags to prevent moisture absorption and degradation during transit.
