JBS Couros launches antiviral leather


Leader in the leather processing market introduces brand-new JBS V-Block innovation with Silver microparticles to produce leather that inactivates microorganisms and infections including Covid-19

SÃO PAULO, July 22, 2021/ PRNewswire/– JBS Couros has revealed the launch of JBS V-Block technology, which suspends the SARS-Cov-2 virus, the cause of Covid-19. At processing phase, a silver microparticle additive is added to the leather covering supplying it with antiviral qualities.

“Our leather has undergone scientific tests that prove the inactivation of the SARS-Cov-2 infection. The application of this new innovation sets a new requirement in leather production. It not just suspends the spread of infections consisting of Covid-19 however assists in the preservation of the material making it ideal for use in surface areas that are utilized regularly or enter into contact with a variety of individuals meaning there is prospective increased direct exposure to Covid and other infections, such as car, seating and furnishings steering wheels or products such as clothes, bags and wallets.”, says Guilherme Motta, president of JBS Couros.

In tests conducted in the level 3 biosafety laboratory (NB3) of the Institute of Biomedical Sciences of the University of São Paulo (ICB-USP), the product revealed 99% inactivation of the SARS-CoV-2 virus in 30 minutes from contact with viral particles.” The use of this innovation increases the contact surface area of silver and its prominence in the leather, enabling antiviral action,” says scientist Lucio Freitas, who took part in the tests of the brand-new material. The tests were made in accordance with the international standard ISO 21702, which establishes the most proper techniques to find antiviral activity in plastics and non-poral surface areas.

The microparticles are built from the synthesis of silver salts – a component chosen for their recognized antiviral action – and stabilized by synthesis innovation. “Silver microparticles are able to suspend the infection by two mechanisms: in its membrane – where they break this external finish of the virus and suspend its entry into the host cells and, in RNA (or DNA), where they oxidize the hereditary product of the exposed virus, inactivating its reproduction capacity”, says products scientist Daniel Minozzi, creator and director of Nanox, a company concentrating on new products and antimicrobials that developed the additive used by JBS Couros.
