Import Direct Yellow 142 — Buy in Bulk from Supplier in India

Direct Yellow 142 is an azo-based direct dye used for coloring cellulosic fibers, plastics, and water-based coatings. It is supplied as a fine, free-flowing powder with a maximum moisture content of 2.5% and a particle size distribution of 80% passing 150 microns. The dye exhibits high solubility in water and polar solvents, with a maximum absorption wavelength of 415 nm in aqueous solution, giving a bright yellow hue.

The chemical structure is based on a diazotized aniline derivative with a sulfonated naphthalene system, which enables strong affinity for cotton and paper substrates. It meets the standard colorfastness requirements for non-illuminated applications, with a wet rubbing rating of 3 to 4 and lightfastness of 4 to 5 on the Blue Wool Scale. Typical formulations include 95% minimum dye content, with less than 1% insoluble matter and no detectable heavy metals above 5 ppm.

Buyers include textile mills producing low-cost cotton goods, plastic manufacturers coloring polyethylene and PVC, and coating formulators for interior paints. The product is packed in 25 kg multi-wall kraft paper bags with inner polyethylene lining to prevent moisture absorption. Trade terms include FOB Mumbai or CIF destination ports. Minimum order quantities are typically 100 kg per shipment, with lead times of 15 to 20 days after payment confirmation.

The supplier does not claim to produce Direct Yellow 142 in-house. Its role appears limited to sourcing from third-party chemical manufacturers and handling export logistics. No quality control data, batch records, or test reports are referenced in the listing. The absence of response metrics suggests limited buyer communication capacity, and no certifications such as REACH, GOTS, or ISO 9001 are mentioned.
