CORIFOB FLEX is a waterproofing fatliquoring agent based on fatty synthetic substances. It is used to produce soft and medium soft articles for full grain leather, suede, leather goods and garment.
CORIFOB FLEX is used in percentages that can vary from 2 to 12% referred to shaved weight. We recommend to use in final 2.5 – 4% of basic chrome sulphate and to run at least 60 minutes to fix the CORIFOB FLEX and to develops the waterproofing effect. The running time can be increased for thicker leather.
For pastel shades or white leather other bi-tri metallic salts can be used in substitution of chrome, like aluminium or zirconium.
The final washing is very important for an optimal result, to eliminate the eventual salts present in the leather. CORIFOB FLEX is light fast, therefore it is suitable also for the fatliquoring of white or pastel shade leather.
