Application performance

TANINTAN BLA is a polymer retanning agent containing special components, which can be used to retann all types of leather; its electrolyte resistance and stability are good, the range of application is wide, and the chromium content of the waste liquid can be very low after use; its composition makes it not quickly combine with the surface of the skin, it has good permeability, it can make the skin fiber bundle dispersed more evenly, the leather grain surface of the retanned leather using this product is smooth and smooth, the feel is soft and flexible, and the uniformity is good.

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

Suggested Usage

The product can be added before and after chrome retanning, during neutralization, after neutralization, or before and after fatting. After adding the neutralizer for 30 minutes, the product can make the skin surface flatter and almost no thickening, and after neutralization, the use of TANINTANBLA with 3-6% of the weight of the leather will make the leather fibers more dense, and the skin body will be fuller and elastic.

TANINTAN BLA can also be used before or after fatting to give the leather a firmer grain without hardening the skin.

Safe storage and transportation

・We recommend storing in 5C-35"C, avoid freezing and overheating, stir well before use, and close the lid after use.
