Properties

TRUPOTAN BIO-05L is an innovative chemical obtained by modification of natural occurring polymers. Its molecular weight has been adjusted in a narrow range.

Thanks to its anphoteric character, TRUPOTAN BIO-05L will produce really different effects on leather depending on the adjusted application parameters (pH, temperature, ionic character …).

TRUPOTAN BIO-05L is compatible with most of retanning agents and fatliquoring chemicals used in the leather processing.  But always we recommend to check stability when using TRUPOTAN BIO-05L together with vegetable extracts in the same bath and specially at low pH values.

TRUPOTAN BIO-05L as a retanning agent in the production of splits and suede articles, extreamly improves the buffing capacity of the leather and provides really short an regular nap. Higher dosages will bring much firmer articles.

Application

In the retanning of splits, dossage will be adjusted between 4% and 8% on shaved weight. When higher the dosage, firmer the leather dossage of  2% - 4%.

In the retanning of grain bovine leather for shoe upper, dossage will be adjusted between 2% and 4% and better aplication point will be in the neutralisation stage.

Storage stability: This product can be stored for up to one year, if temperatures below 5 °C and above 40 °C can be avoid
