Properties

TRUPOTAN TCH is vegetable based tanning and retanning agent which when compared to other vegetable based tanning products , produces crust leathers with cleaner and brighter shades. In addition leathers exhibit improved fastness properties to both to light and heat yellowing .

Leathers retanned with TRUPOTAN TCH show excellent dyeing behaviour, allowing much cleaner and brilliant shades to be achieved than when utilising mimosa or quebracho based products.

TRUPOTAN TCH can be utilised as a main tanning agent, or in combination with other vegetable tanning agents, thus allowing  pale clean crust leathers to be manufactured with outstanding grain characteristics and excellent fullness.

In the retanning stage TRUPOTAN TCH can be used alone or in combination with other vegetable based retanning agents or syntans, as well as with resin or polymer based materials .

Application

TRUPOTAN TCH can be used to good effect in admixture with TRUPOTAN GSX where it will facilitate the production of full tight leathers with low stretch.

Quantities to be used:

5%-10% as a retanning agent
20%-30% as a tanning agent
