Application performance

● TANINTAN BLK: It is a amphoteric acrylic polymer retanning agent, which can be used to retann all types of leather;

● It can be used before neutralization and before and after chrome retanning, bringing a solid feel to the leather body.

● This product can improve the absorption rate of fatliquors after fatliquor.

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

Suggested Usage

● It is recommended to use TANINTAN BLK with 24% shaved leather weight when blending.

● After the fatting is completed, the use of TANINTAN BLK with 1-2% weight can increase the absorption rate of the fatliquor, make the grain surface flat and thin, and at the same time make the subsequent top dye obtain a deeper color.

Safe storage and transportation

● We recommend storing at 5C-35°C, avoid freezing and overheating, stir well before use, and close the lid after use.
