  • VENFIXDF is a cationic fixing agent for anionic dyes used in leather industry to enhance wet fastness of dyed leather. It is based on methylol amides

Characteristics

  • AppearanceClear colourless to pale yellow liquid
  • pH of 10% solution3 ? 0.5
  • Solid content50 ? 1%
  • Compatible withCationics, nonionics

Special Features

  • VENFIXDF is used in the after treatment of dyeing with all anionic dyes, to the extent of 1 - 1.5% on shaved weight & 2 - 3% on dry weight
  • IMPORTANTTo be used with caution on grain leathers that are finished with anionic products, since the cationic charge on the leather surface can adversely affect penetration of finishing season

VENFIX - DF is a cationic fixing agent for anionic dyes used in leather industry to enhance wet fastness of dyed leather.

VENFIX - DF is used in the after treatment of dyeing with all anionic dyes, to the extent of 1 - 1.5% on shaved weight & 2 - 3% on dry weight.

Use the sample form and name Venfix - Df together with the intended process, substrate and any EO/PO, HLB, cloud-point or active-content window. Laboratory quantities ship after a short company check, with SDS and TDS when those boxes are ticked. A catalogue grade can be confirmed, or a custom batch planned on the Kandla plants.

Yes. SDS, TDS and COA for Venfix - Df are issued to identified companies after a short verification — they are not open downloads. COA is lot-specific; if a commercial lot has not been allocated, typical TDS data is sent first and the COA follows the production batch. Request files from the documents form.

Dyna Glycols custom-manufactures when a catalogue point in Dyes Fixers is close but not exact. Write the hydrophobe or acid/alcohol pair, the analytical window, pack and annual volume. Once a trial lot of Venfix - Df is approved, freeze the TDS so later drums match the evaluation.
