Support the tanning process to achieve more uniform and reliable leather performance

Tanning auxiliaries support the beamhouse process by improving process control, uniformity, and efficiency. They help optimize soaking, liming, deliming, and bating steps, ensuring better fiber opening, cleaner pelts, and consistent preparation for tanning. The result is more reliable leather quality, improved performance, and reduced process variability.

Implenal® DC-Liq

Is employed in chrome tannages as a masking and basifying agent. It improves the uptake and fixation of chromium salts, which makes it possible to reduce the amount of chrome that needs to be applied. Can be used to enhance the fullness and tightness of the grain of many types of leather. Leather treated with Implenal® DC Liquid has superior perspiration resistance, and it is less prone to degradation due to the presence of acids.

Feliderm® MGO

Feliderm® MGO is a special magnesium oxide with a specific particle size distribution. It is used as a safe and effective basifying agent during the chrome-tanning process. Feliderm® MGO contains low levels of impurities and the controlled particle size supports its gradual and controlled dissolution for a slow and controlled basifying action. As a self-basifying agent for chrome tanning, it provides a slow, gentle rise in pH during basification. The carefully controlled particle size distributes the chrome uniformly and it provides a safe and consistent performance. The resulting leather shows a high shrinkage temperature

Neutrigan® MOS

If you’re searching for an effective basifying agent for use in chrome tanning, look no further than Neutrigan® MOS. This tanning auxiliary is slow acting: it works continually to ensure that the chrome is evenly distributed in the leather, which gives it a superior grain. It causes a slow, constant increase in the pH of the tanning liquor. If the magnesium oxide is too soluble, the pH undergoes a large initial increase and then decreases towards the end of the tanning process. With Neutrigan® MOS, the final pH is approached gradually, and always from below. This prevents sharp fluctuations in pH.
