Application performance

● When retanning with TANINTAN BLE, the leather can be soft, round and very full, and the filling effect is uniform. Because TANINTAN BLE does not have the astringency of the usual vegetable tanning agents, it gives the leather a smooth, fine grain while maintaining excellent fullness.

● TANINTAN BLE is used for retanning and filling leather that needs to be soft, and the use of tannin gum can make the leather surface produce natural and delicate lines while maintaining excellent fullness.

● TANINTAN BLE. has good lightfastness, excellent heat resistance and yellowing, and has a certain bleaching ability, which can be used for white leather and light-colored leather retanning.

Suggested Usage
