Finishing

Fillers, Coverage, Matting Agents

They are used in ground composition to improve the leathers grading due for their coverage. Improve the finishes covering. Give matting effect, opacity of crack/breaking effect. Excellent result is achieved in corrected grain, vulcanized split, hides having superficial scratches. When we need to decrease the thermoplastic effect. They improve the embossing film properties due to their hardness.

Sulfited Fatliquors

Sulphited fatliquors are produced by reaction of fats with sodium bisulphite. In general they give smooth and very soft leathers but no filling effect. Provide hang hides with high inner softness. Excellent stability to tanning baths and electrolytes (acid and alkaline). can be used in all production stage, like tanning or retanning. Excellent penetration, distribution and fixation of fat. Can be used as single fatliquor. Specially TTK or CMT. Complete relaxation of the fibers cause excellent milling properties. Light fastness will depends on the type of fatliquor.
