POLAR OIL S40 is a synthetic based fatliquor with moderate resistance to electrolytes and good light-fastness. It is possible to achieve leather softness comparable to a sulphited fatliquor.

Thanks to its characteristics, POLAR OIL S40 can be added to the baths without diluting beforehand because it penetrates rapidly and deeply.

POLAR OIL S40 is particularly recommended for high quality aniline nappa or velour because it enhances softness and promotes even distribution of tanning matter.

The product gives a soft and elastic feel to the leather, with a very low specific weight. Colours are pure and bright. The percentages of use vary from 2 to 10% depending on the article and on the wished effect.
