DESCRIPTION
Nonpolluting tanning agent which can efficiently eliminate Basic Chromium Sulphate with great ease. SERTAN WT is compatible with other anionic synthetic, natural tanning and retanning agents. It is highly recommended in the manufacturing of all types of chrome free and wet white leathers. Combinate with vegetable tanning extracts, resultant leather indicates extra softness with increased fullness without altering vegetable character. SERTAN WT can be effectively used in salt free tanning system. It induced excellent plumping effect in the hides which results into efficient splitting and shaving. It imparts excellent filling effect in the loose parts of the hide which can minimize usage of polymers and resins. It also eliminates usage of Glutaraldehyde based tanning agents. Leather tanned with SERTAN WT possesses outstanding dyeing ability with brilliant dyeing affect. It has low specific gravity and the same can be also used in the manufacturing of very soft articles.

DESCRIPTION
Can be used as a tanning or retanning agent.
We will use SERTAN AL for Wet White tanning process or fine fur with excellent tanning results, obtaining contraction temperatures necessary for the desired items. The product consolidates the skin fibers, obtaining good firmness.
SERTAN AL, used as a retanning agent preferably before the neutralizing, we will give whiter leathers, good compactness and fullness that will help us to obtain leathers with closer plush after grinding. The product helps to obtain more intense and even dyes. We can use it for fixing the water-repellent oils by providing the required flexiometries.
It consolidates the fiber structure, and gives a tighter and smoother grain, good filling. Better response to dyeing, improving the intensity and evenness of dyes. Very suitablefor white or pasted shade.
