Chrome-free leather solutions by TFL – processing in an ecological and sustainable way

TFL is the pioneer of chrome-free leather technology for automotive leather manufacturers since 1990. In the meantime, and due to the potential risk of chromium VI formation in accessories, there is an increasing demand for metal-free shoe upper & leather goods articles.

The majority of chrome-free leathers today are pre-tanned with modified glutaraldehyde and, although glutaraldehyde (GA) is considered a hazardous chemical, it can be handled in a safe way in order to eliminate risks to workers, consumers and the environment:

  • GA is a reactive molecule and the reaction is completed by basifying after the pre-tanning step, resulting in excellent exhaustion.
  • Any possible residual GA will react with proteins present in the processing float, without impacting the efficiency of waste water treatment.
  • GA pre-tanning does not contribute to free aldehyde readings in the final leather and there are no hidden post-reaction effects in later process steps, or in the product life cycle.

SELLATAN® LI-G Liq - your state of the art pre-tanning solution

Pre-tanning based on modified glutaraldehyde is the most efficient tanning chemistry to turn collagen into leather. TFL has therefore developed SELLATAN® LI-G Liq with the following features & benefits:

  • GHS label classification and storage obligation remains unchanged after March 1st 2018
  • Reduced GA odour during the pre-tanning process improves workplace health and safety
  • Excellent penetration and distribution throughout cross-section – even on full substance pelts
  • High efficiency leads to an excellent exhaustion of residual GA
  • Slow drying out of wet-white with good wetting back behaviour
