In May 2020 in production at several tanneries technological trials of an amide based agent for preventing liming wrinkles “Vega RLM” were conducted. The product, which is also active in hard water, was tested on bovine with a weight of 35-40 kg, 22-25 kg, in comparison with the tannery anti-wrinkle agent. The trials were carried out with a positive result: wet-blue wrinkles were weak; there were a low percentage of near-belly liming wrinkles. The wet-blue obtained during trials did not differ in quality and appearance from the tannery standard wet-blue. In the near future, we are planning to purchase VEGA RLM for extended testing.
