Tannic Acid and Gallic Acid
Tannic Acid and Gallic Acid are natural extracted substances from gallnuts, tea leaves and other plants. Both materials are safe and environmentally friendly substances.
Tannic Acid is used in wide range of applications such as water treatment, steel corrosion treatment, dying, beer manufacturing and pharmaceuticals.
