从India供应商批量进口2:1 Metal Complex Dyes

Krishna Impex, based in Maharashtra, India, supplies a catalogue of 2:1 metal complex dyes covering multiple acid dye classes. The listed range includes Acid Yellow 151 (CAS 12715-61-6), Acid Orange 60 (CAS 30112-70-0), Acid Red 357 (CAS 61951-36-8), Acid Blue 193 (CAS 12392-64-2), Acid Green 73 (CAS 12219-93-1), Acid Violet 90 (CAS 6408-29-3), Acid Brown 282 (CAS 12219-65-7), and Acid Black 194 (CAS 63931-02-0), among others. Each dye is identified by its Colour Index number and CAS registry, giving buyers a clear basis for cross-referencing with international colour standards.

2:1 metal complex dyes are formed by coordinating one dye molecule with two metal ions, typically chromium or cobalt, which produces strong lightfastness and washfastness compared to non-metallised acid dyes. Typical industry grades for these dyes carry a standard dye strength of 100% or 200%, with moisture content generally below 5% by weight. The powder form is standard for bulk handling, and solubility in water is a common specification buyers should confirm, as it varies by shade and affects dyeing bath preparation.

These dyes are widely used for colouring nylon, wool, silk, and leather, where moderate to good wet fastness is required. Textile mills, leather processors, and carpet manufacturers form the primary buyer base for this product category. Buyers should request Krishna Impex's specific technical data sheets, packaging formats, and minimum order quantities before placing a trial order, as the listing does not detail these trade terms.

Krishna Impex operates from B-10, Om Sai Industrial Estate, Bhayander East, Phatak Road, Thane 401105, Maharashtra, India. The supplier profile is listed with a harbour trust tier, meaning the platform has limited verification data on this company. The response rate shown is 0.00 with no recorded average response time, so buyers should allow extra time for initial contact or use direct phone or email channels if available.

The listing presents Krishna Impex as a supplier of specialty acid dyes, specifically 2:1 metal complex dye variants. The supplier tier is marked as 'imported', indicating the company sources or deals in products that may be manufactured elsewhere, though the listing does not specify whether these dyes are produced in-house or procured from third-party manufacturers. Buyers seeking assurance on production origin, quality management certifications, or export history should request documentation directly from Krishna Impex before committing to large orders.
