Emdirenal PAL24N is a special tanning agent that can be used as a pretanning and retanning agent.
Emdirenal PAL24N is specially developed for the manufacture of leathers with high washfastness, and high perspiration resistance. By the use of Emdirenal PAL24N heat and light fastness of the final articles are neatly improved.
When used in pretanning Emdirenal PAL24N tanning (vegetable, chrome, zirconium or semi-chrome) liquors penetrate in a more uniform and rapid action and fuller and softer leathers are obtained. When used after tanning the resulting leathers will show firmer, smoother grain with good fullness.
Emdirenal PAL24N is completely compatible with mineral, vegetable and synthetic tannins.
Emdirenal PAL24N does not cause yellowing of neither the leather nor the wool.
