In February 2021 the company Shebekinskaya industrialnaya khimiya, LLC (Russia) at one of the tanneries has tested the recipe of the patent article from the Trend book "Spring/Summer 2022" of the company Pielcolor, S.L.U. (Spain). The obtained article was assessed positively. The specialists of the tannery noted the high covering power of the chemicals AA 4641, ML 2803 and the pleasant touch of the coating, which is achieved thanks to the use of matt urethane UR 1693 and wax emulsion AA 4350. The tannery is planning to send an order for these chemicals for extended trials.
