]]>La technologie des films Pure Zone développés par Hexis s’est montrée efficace pour combattre les coronavirus*.
Les caractéristiques des films de protection antimicrobienne PUREZONE® réduisent de 95 % après un quart d’heure de contact, et près de 99,9 % après une heure de contact (par rapport à une membrane non-traitée) la présence des coronavirus*.
Sans danger pour le contact avec la peau et puissants, les films Pure Zone restent transparents après application. Ils sont esthétiques, n’altèrent pas les supports, et protègent pendant de nombreuses années. « Les ions d’argent réactifs, contenus dans les films PUREZONE®, vont rapidement inhiber les bactéries et coronavirus*, empêchant ainsi leur prolifération entre deux protocoles de désinfection » précise Christophe BAUDRION, Directeur du Laboratoire R&D HEXIS.
Retrouver dans notre boutique les films virucides antibactériens Pure Zone sous divers formats : au mètre, en format prédécoupé, pour les poignées de porte, pour les interrupteurs… existe en mat et en brillant !
