The company Shebekinskaya industrialnaya khimiya, LLC has tested a dyeing-fatliquoring recipe of white crust using: "BF/10" — a white sulfonic leather tanning agent with a strong filling effect and bleaching effect, as well as "SMH-400" — a new electrolyte-stable fat liquor for chrome and vegetable tanning leathers with excellent penetrating ability, which, due to its high stability against acidic water, electrolytes and chromium salts, can be used in a pickle bath in chrome tanning. The fat liquor "SMH-400" has a good ability to soften and lubricate leather fibers, high light resistance and resistance to oxidation. It is well fixed in the leather. It has very good bath exhaustion. It evens the colour without reducing its saturation. It is used for fatliquoring nappa, light lining, split, light harness leather, as well as light crust. The leathers, treated with "SMH-400", have tight grain and pleasant touch. The trials had a positive result.
