Application performance

● TANINTAN BLC is a polymer retanning agent containing special components, which can be used for retanning all types of leather, it is acid resistant and chromium resistant, so it has a wide range of use, and its structure can help the absorption and fixation of chromium, so the waste liquid chromium content is very low after using this product; its composition makes it not quickly combine with the surface of the skin, it has good permeability, the leather grain of the retanning with this product is flat and compact, not rough, soft and flexible, and the uniformity is good.

● This product has excellent lightfastness and can be used in the production of light-colored leather.

Suggested Usage

added before and after chrome retanning, neutralization, neutralization or before and after fatting, adding this product 30 minutes after adding the neutralizer can make the skin surface flatter and almost no skin thickening, after neutralization, the use of TANINTANBLC with 3-6% of the weight of the evenly shaved leather, the obtained leather fiber will be more fine, the leather body will be more full, compact and elastic.

● TANINTAN BLC can also be used before or after fatting to achieve a firmer grain of leather without hardening the skin.

Safe storage and transportation

● We recommend storing at 5C-35"°C to avoid freezing and overheating, stirring the birch evenly before use, and closing the lid after use.
