Usage and dosage:

After the tanning agent is completely penetrated, add it to the drum in powder form twice. The dosage depends on the pH of the pickling solution, the thickness of the bare skin, the amount of tanning agent and the pH value required at the end point. The recommended dosage is 0.4-0.6%.

Performance characteristics:

1. The alkali extraction effect is mild, the pH value of the bath is steadily increased, and the tanning agent is evenly distributed.

2. The leather body is firm, the grain surface is fine, and the tanning agent absorption rate is high.

3. The alkali extraction process is simple and easy to control, saving manpower.
