The two most commonly used technique recommended

Bath with the added fat or carry out in the new bath afterwards. You can also combine these two methods to obtain the best performance.

Post-processing method: After the end of all the complex tanning process, you then change new bath with liquid ratio --200-1000%, temperature --60°C, adjust the pH≥4, add GOODNICE weighted 4-8% of shaved leather, and rotate 45 minutes, when GOODNICE is almost absorbed, then add formic acid, adjust the pH to 3.0, at last, control water, wash by conventional methods. This is a standard formula.

If productive waterproof leather, you must fix it before or after adding GOODNICE and use it in the proceed of adding fat. In this method, GOODNICE weighted 4-8% of shaved leather is added before, after or simultaneously with fatliquor, not need to change the production process. The advantage of this method is that GOODNICE can penetrate deeply into the leather fibers, and it is an approach of producing waterproof leather and directly producing suede leather.

Notes:

Dilute with water before use.

We strongly recommend the use of waterproof fatliquor in order to improve the water resistance of leather,especially the dynamic water resistance.

We also strongly suggest that first check the compatibility of GOODNICE before use, if it is mixed or bathed with other chemicals.
