从India供应商批量进口Acid Red 34

Acid Red 34 is an acid dye used to produce vivid red shades on protein and polyamide substrates, supplied by Krishna Impex from India. The product carries CAS number 6360-04-9 (also rendered as 09-04-6360 in source documentation), identifying it as the sodium salt of a monoazo chromophore with the molecular formula C16H12N4Na2O7S2 and EINECS number 228-821-1. It is offered in powder form for industrial colouration processes. The dye exhibits good water solubility, a prerequisite for exhaust and continuous dyeing applications on wool, silk, nylon, and leather. Its azo-based chemistry provides strong substantivity to cationic sites on amphoteric fibres, giving moderate to good build-up with controlled migration.

The standard commercial form is a fine, free-flowing powder with typical moisture content below 5 percent to ensure storage stability and accurate weighing in batch preparation. Light fastness generally ranges from 4 to 5 on the ISO Blue Scale for wool, with wash fastness at 40 degrees Celsius typically achieving 4 to 5 on the ISO Grey Scale for change and staining. The dye is compatible with selected acid milling and 1:2 metal-complex dyes for shade building, though compatibility tests are advised before production runs. Typical purity by spectrophotometric assay is 60 to 80 percent depending on standardisation strength, with the balance comprising sodium chloride, sodium sulphate, and dispersing agents. pH stability in application baths is normally maintained between 4.5 and 6.0 using acetic or formic acid.

Primary buyers include textile commission dyers, carpet manufacturers, leather tanneries, and specialty paper mills seeking brilliant red shades with acceptable fastness at moderate cost. In plastics, Acid Red 34 finds limited use in nylon masterbatch coloration where migration resistance is less critical. Krishna Impex lists this material with flexible order quantities, though exact MOQ, price bands, and lead times are not specified in the available data and should be confirmed directly with the supplier. Packaging is described as tailored for transit integrity, with FOB and CIF terms mentioned as options. Response rate data shows zero recorded responses, so buyers should allow additional time for initial contact and negotiate sample availability before committing to bulk orders.

The supplier is classified under the imported tier with a harbor trust designation, indicating a baseline verification level within the marketplace framework. No response rate or average response time data is recorded, which suggests buyers should initiate contact with clear product enquiries and allow for follow-up communication rather than expecting immediate replies.

The company profile does not disclose founding year, employee count, annual revenue, or named clientele. Its listed product, Acid Red 34, is positioned for textile, paper, leather, and plastics applications.
