Rockaltal F

Rockaltal F is a special deliming agent which can be used singly for deliming stage in any type of leather, in drum, paddle or pit.
Rockaltal F delimes the pelt layer by layer and produces easily soluble calcium salts and is able to dissolve any lime blast which is already existing. It can also be used in short float processes. Pelts delimed with Rockaltal F have a clean and flat grain with good tightness.
