Applications & Recommendations
Munfix GR (SAFE ACID) is suitable for all kinds of leathers wherever Formic acid 85% is used. It can replace formic 85% in any formulation.
Munfix GR (SAFE ACID) is exothermal just like any other acids commonly used in tanneries. When water is added, it increases the temperature of the solution during the diluting process.
Munfix GR (SAFE ACID) should be diluted with water with the portion of 1:10 exactly the same as Formic acid. 10% solution can be safely used to lower the pH during wetting back (re-chroming).
Advantages
Non-polluting, eco-friendly and direct replacement for 85% strength Formic acid in any formulations. (No need to change the formulation)
An additive which imparts more smoothness to the leather surface than formic acid.
Unlike formic acid, this product is no corrosive and easy and safe to handle.
Smell of acids does not remain in leathers after the final washing step.
It produces less hydro & Oxy groups thus the leathers will be stronger and darker in dye shades after fixation.
It accelerates acid penetration in the pickling stage. It leads to tighter, fuller and smoother grains in wet-blues after chrome tannage.
Lower the BOD & COD content in the effluents than Formic acid.
It does not lead to evaporate any smell of fumes during the dilution, because the product does not contain Sulphuric, Hydrochloric or Formic acids.
The level of free formaldehyde content as an impurity is significantly lower than standard formic acid.
Storage Conditions
The product should be well sealed and must be stored in covered area between 5-25°C. Freezing and direct sun light must be avoided.
