FAQs - Frequently Asked Questions

What is the most used vegetable tannin extract for tanning and retanning leather in the world?

The most used vegetable tannin extract in the world is Acacia Tannin.

Acacia tannin is extracted from the bark of the Black Acacia tree, which comes from forests located in southern Brazil. Seta's Acacia Tannin extraction process is unique, innovative and totally sustainable.

Acacia tannin is of the condensed or catechin type.

Acacia Tannin, in addition to being a biodegradable product, is very versatile, as it can be used both in the tanning of chrome leathers of any thickness and softness, as well as in the tanning of 100% vegetable articles of any type. It can be used both to produce light and soft vegetable leathers and metal free type, as well as heavy items such as soles and shoe soles. Very light and dark vegetable leather can be produced due to the different types of shades of each line that Seta produces. It is easy to use as it has good water solubility, good penetration speed, can be used in combination with other plant extracts and synthetic tannins, improving the distribution of retanning agents, dyes and fatliquors. It can be used in any vegetable tanning system, whether it is fast in drums or static in tanks. Acacia Tannin brings numerous benefits to leather as a natural look, “burn” properties, grain tightness, filling, excellent sandability and print retention.

Acacia tannin is essential in the production of any type of vegetable leather, including shoe soles, midsole, soles and straps for belts, straps for pets, saddles for horses, artifacts in general, insoles, heels, sandals. leather, bags, etc.
