Acid Brown 425 is a yellowish brown synthetic dye primarily formulated for application on aniline leather, including shoe uppers, upholstery leather and leather garments. The product adheres strongly to protein fibres, delivering consistent colour penetration with minimal migration during application. It is also compatible with wool, nylon, silk, paper and ink substrates, as confirmed by its listed end uses.
The dye belongs to the acid class, which typically exhibits good lightfastness and washfastness on leather when applied under controlled pH conditions. Standard acid dyes for leather operate within a pH range of 3 to 5, with typical solubility in water exceeding 50 g/l at 25°C. Acid Brown 425 shares synonyms such as Acid Havana 2RL, indicating its established use in leather finishing formulations.
This dye is sourced by manufacturers of leather goods, footwear and textile products requiring uniform brown shades with reliable colour consistency. Buyers should confirm compatibility with their specific substrate and processing conditions, as variations in fibre type and pre-treatment can affect uptake. The product is supplied in powder form, standard for acid dyes, and is typically packed in 25 kg multi-layer paper bags with inner polyethylene lining to prevent moisture absorption.

Before ordering Acid Brown 425 from Viana Chemicals, confirm the dye’s compatibility with your specific leather or textile substrate. Request a sample for lab testing to assess colour consistency, fixation and fastness properties under your processing conditions.

Conduct quality checks upon receipt to ensure the dye meets specified colour and solubility standards. Request a certificate of analysis for each batch, including tests for lightfastness, washfastness and heavy metal content. For leather applications, perform a trial run on a small batch to evaluate performance before full-scale production.
