Testing “Dowell” acrylic impregnation agents for the article with impregnation.

27.05.2025

“Dowell” acrylic impregnation agents have been tested in the article with impregnation at one of the Russian tanneries. A combination of three products was tried: • «Dowellic RA 1861» - ultra-fine acrylic resin with good penetrating ability, especially for impregnation of leather, which keep softness and tightness of the leather without forming a film on the grain; easy to buff. In combination with «Dowellic RA1863» or «Dowellic RA1865», the impregnation efficiency is improved and the tendency to looseness in loose areas is eliminated;...

Testing the recipe of the article “Shoe crust” with the use of “Dowell” chemicals.

23.05.2025

In an experimental shop at one of the Belarus tanneries, a recipe has been tested for obtaining the article "Shoe Crust" in thickness of 2.0 - 2.2 mm using “Dowell” chemicals (China): • «DOWELLTAN RV13» - a retanning agent based on acrylic resin. In chrome tanning «DOWELLTAN RV13» significantly improves fullness and density of grain and reduces stickiness, has an excellent dispersing effect and accelerates the penetration of vegetable tannins. It can also be used instead of vegetable extracts. It has excellent light resistance and heat resistance, and has bleaching ability;...

Testing the dyeing-fatliquoring recipe with the use of Shebekinskaya industrialnaya khimiya, LLC chemicals.

21-05-2025

A technological visit had been conducted at one of the tanneries in Belarus, during which the dyeing-fatliquoring recipe was tested for articles: "Cow lining" and "Shoe crust" for further finishing in a thickness of 1.2-1.4 mm, with a positive result. The recipes were tested using chemicals from Shebekinskaya industrialnaya khimiya, LLC (Russia):

«SMH-470» - synthetic fat liquor of anionic character;
«SMH-473» - fat liquor based on natural and synthetic sulfonated fats;
«SMH-477» - fat liquor based on sulphited and sulfonated natural and synthetic oils that comply with the requirements of the REACH regulation;
«SMH-479» - NOVELTY, mixture of natural, sulfonated and synthetic oils that meet the requirements of the REACH regulation. The product is developed for fatliquoring of chrome-tanned, vegetable-tanned and mixed-tanned leathers. On all types of the leather, the fat liquor is evenly distributed over both the area and the thickness of the leather, giving the leathers oft and tight grain, pleasant touch, while increasing elasticity and tensile strength. The high concentration of the solids allows to achieve good fatliquoring results with minimal consumption;
«SMH-478» - NOVELTY, concentrated fat liquor based on a mixture of natural, synthetic, sulfonated and sulphited natural oils that meets the requirements of the REACH regulation. It is used for soft filled leather articles. It is recommended to use it with other fat liquors to give softness and natural touch. On all types of leather, the fat liquor is evenly distributed over both the area and the thickness of the leather, giving the leathers oft and tight grain, pleasant touch, while increasing elasticity and tensile strength. The high concentration of the solids allows to achieve good fatliquoring results with minimal consumption. The composition does not lighten dyes, which allows to get bright, saturated colour.

All the crusts were positively evaluated by the tannery managers. The recipes were given over to calculating the cost of treating. It is planned to order new chemicals for extended trials.
