Ich habe die hydrophobe PTFE-Membran für einen etwas unkonventionellen Einsatz genutzt und sie zur Abdichtung von Bohrlöchern an den Rückleuchten meines Ford Edge verwendet. Diese Löcher habe ich gebohrt, um Staunässe zu beseitigen, die sich in den Leuchten angesammelt hatte. Nachdem die Rückleuchten vollständig getrocknet waren, habe ich die Membran eingesetzt, um die Öffnungen abzudecken. Das Ergebnis: Die Membran lässt Luft zirkulieren, verhindert aber zuverlässig das Eindringen von Wasser.Das Produkt funktioniert einwandfrei und hält bereits seit mehreren Monaten perfekt – selbst bei wechselnden Wetterbedingungen. Eine clevere und äußerst praktische Lösung für Feuchtigkeitsprobleme. Absolute Empfehlung für ähnliche Einsatzzwecke oder als flexible Dichtlösung!

Held up well after first pressure cook, no issues with sticking to PP lid. However, awaiting results of LC and grain jars after inoculation before I can confirm sterile technique
