The direct method to produce sheep nubuck requests an important dispersion of all the products, like syntans, dyes and fatliquors. SELLASOL KM liq. in the retanning improves the dispersion effect on the leather and the dyeing is better levelled throughout the cross-section. This improves the buffing properties.
Using SELLASOL CR liq. at the end gives shorter fibre, with a good writing effect.
