Decal AL contains organic acids who alow the complete deliming of leathers and avoid also any blowing up problems, which are frequent by using acid products during the deliming process.
Decal AL has the properties to complex and to solubilize te ions Ca+ + MG + + which are both precipitated or fixed between the leathers fibres.
The leather have a clean and very strehed grain. Decal AL has strong deliming action and it can fast penetrate in the leather.
These caracteristics allow the prouct to delime leathers with a full thickness.
