Buy & Import ACID BROWN 75 from Viana Chemicals - India Wholesale Supply

Viana Chemicals supplies ACID BROWN 75, a synthetic azo dye with molecular formula C26H18N4Na2O10S2, for textile, leather, and paper coloration applications. This water-soluble acid dye is formulated for affinity to protein fibres and polyamide substrates, producing consistent brown shades with level dyeing characteristics. The product is manufactured in Ahmedabad, India, and distributed in standard drum or bag packaging for B2B industrial users.

The azo chromophore structure provides moderate to good light fastness and wash fastness on wool and nylon, with typical exhaustion rates of 80-95 percent at pH 4.5-6.0 under standard acid dyeing conditions. Metal complexation is not required for this pre-metallised or conventional acid dye type, though the exact classification (leveling versus milling acid dye) should be confirmed with the supplier. Compatibility with other acid dyes in combination shades depends on similar dyeing profiles and molecular weight.

ACID BROWN 75 serves wool carpet manufacturers, nylon hosiery producers, leather tanners, and specialty paper mills requiring brown coloration with reasonable fastness at moderate cost. Buyers should request the Colour Index constitution number, physical form confirmation (powder versus liquid), and solubility data at 20 degrees Celsius and 60 degrees Celsius. Certificate of analysis for each batch should verify strength against a standard, pH of solution, and moisture content.

Frequently Asked Questions About ACID BROWN 75 from Viana Chemicals
The Colour Index name should be confirmed directly with Viana Chemicals, as C.I. Acid Brown 75 is a specific commercial designation that may map to different chemical structures across manufacturers. Request the C.I. generic name and C.I. constitution number to cross-reference with the Colour Index Online database. This ensures colour matching consistency with existing production recipes and avoids metamerism issues with previous dye lots.

Sourcing ACID BROWN 75 from Viana Chemicals - India Import Guide

Before ordering ACID BROWN 75 from Viana Chemicals, request a pre-shipment sample for laboratory dyeing trials on your specific substrate and process conditions. Verify the supplier's MSDS availability in English and local language, with correct GHS hazard pictograms for azo dye classification. Confirm whether the product requires temperature-controlled storage and what the stated shelf life is under recommended conditions.

Ahmedabad offers port access via Mundra or Kandla for sea freight, with air freight possible through Ahmedabad international airport for urgent requirements. Incoterms, lead time, and payment structures must be negotiated directly with Viana Chemicals, as no standard values are fixed in the profile. Clarify export documentation they provide, including certificate of origin, free sale certificate, and any required chemical notification for your destination country.

Quality assurance should include batch-wise certificate of analysis review, comparison against retained standards, and trial dyeing before bulk commitment. For textile applications, conduct ISO 105 fastness testing (light, wash, perspiration, rubbing) on production-scale samples. Consider retaining an independent testing laboratory for heavy metal and restricted substance verification if supplying to brands with stringent chemical compliance requirements.
