VENFIX - DF
VENFIX - DF 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.
Appearance : Clear colourless to pale yellow liquid
pH of 10% solution : 3 0.5
Solid content : 50 1%
Compatible with : Cationics, nonionics
Solubility : Dilutable with water
SPECIAL FEATURES :
• serves to improve the fixation of dyeings made with acid and direct dyes ;
• produces a distinct improvement in the wet fastness properties ( water, wash and perspiration fastness)
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.
IMPORTANT : To 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.
