Properties

TRUPOTAN BIO 02L is an innovative chemical obtained by modification of natural occurring polymers. Its molecular weight has been adjusted in a narrow range.

TRUPOTAN BIO 02L is especially recommended for the retannage of upholstery, car upholstery and  softy footwear and leather goods. Leathers obtained will show full, round and light handles.

TRUPOTAN BIO 02L used in the retanning & fatliquoring stage will improve penetration and distribution of chemicals, getting as a result deeper softnes and better levelling in the final article. Thanks to its amphoteric character, leathers retanned with TRUPOTAN BIO 02L will always exhibit an excellent dyeing behaviour. Dyeings will aways show good levelling and brillance.

TRUPOTAN BIO 02L can be used in the production of waterproofing articles without loss of properties.

Application

Depending on the leather and on the required article, next dosage could be used:

In neutralisation stage:  4% - 6%    -    In retanning stage: 4% - 8%

TRUPOTAN BIO 02L shows good stability into the normal working pH ranger and it’s compatible with most of retanning agents and fatliquoring chemicals.
