Artworks do not fear time. They fear humidity.
Every variation in relative humidity leaves a mark: wood that moves, a paint layer that lifts, a metal that oxidises. Propadyn Museart was created to stop all this — stabilising relative humidity at the value you choose, between 35% and 80%, and keeping it constant over time.
It is the most advanced biocompatible solution for protecting valuable artefacts: passive, safe, Oddy Test certified. On display, in transit, in storage — art remains safe, in every condition.
