从India供应商批量进口Acid Yellow 34

Acid Yellow 34 (CAS 6359-90-6) is an industrial-grade acid dye supplied by Krishna Impex from Maharashtra, India, characterised by a 50% concentration level that suits bulk manufacturing requirements. The dye delivers a vibrant yellow shade with demonstrated lightfastness and washfastness, retaining colour stability under prolonged light exposure and repeated washing cycles. Krishna Impex positions this as an export-grade material for textile, plastics, and coatings applications, with compatibility across multiple substrate types.

Chemically, Acid Yellow 34 belongs to the acid dye class, typically synthesised from diazotised aromatic amines coupled to naphthol or pyrazolone intermediates. The molecular structure confers solubility in acidic aqueous media, enabling uniform exhaustion onto protein fibres (wool, silk) and selected polyamide substrates. Standard commercial grades typically exhibit pH-dependent solubility profiles, with optimal dyeing ranges between pH 4.5 and 6.0. The 50% concentration indicates a standardised commercial strength, common for bulk acid dye formulations rather than pure dye content.

Primary buyers include textile commission dyers, synthetic fibre manufacturers, and industrial coatings producers requiring consistent batch-to-batch colour reproduction. The dye finds particular use in automotive textiles, carpet yarns, and leather finishing where moderate to good wet-fastness properties suffice. Krishna Impex offers this material on FOB and CIF basis, though specific Incoterms, lead times, and minimum order quantities should be confirmed directly with the supplier given the zero response rate recorded.

Krishna Impex operates from B-10, Om Sai Industrial Estate on Bhayander East Phatak Road in Thana, Maharashtra, India (PIN 401105). The supplier carries a 'harbor' trust tier with 'imported' supplier classification, indicating product sourced through import channels rather than manufactured in-house. Response metrics show 0.00% response rate with zero average response hours, suggesting limited outbound communication activity on the platform. No ISO, SGS, or other third-party certifications are independently verified in the profile; the source description mentions these but they are not confirmed credentials.

The listing emphasises export-quality supply with flexible trade terms, though concrete verification signals (audits, transaction history, or buyer references) are absent. Buyers should conduct direct due diligence: request current business registration, active dye import licences, and batch-specific test reports before committing. Krishna Impex does not disclose manufacturing partnerships, warehouse capacity, or quality control protocols in the available data.
