Beyond stabilization: Propadyn Museart passes the Oddy Test with classification

In the microclimatic control of cultural heritage, the stability of relative humidity is vital, as is the chemical purity of the air. We are proud to confirm that Propadyn Museart has successfully passed the rigorous protocols of the Oddy Test, achieving the highest rating for permanent use in exhibition and storage environments.

Why is this result a milestone for preventive conservation?

A humidity stabilizer must "breathe" along with the artworks. Passing the Oddy Test certifies that Propadyn Museart not only regulates humidity with unparalleled precision but does so in a completely inert manner.

Thanks to its advanced composition, Propadyn Museart:

• Is free of acid emissions: no release of volatile organic compounds (VOCs) that could corrode metals or degrade pigments.
• Is safe for noble metals: tests on silver and copper confirm the absence of sulfur compounds.
• Protects lead: passing the lead test guarantees the absence of organic acids, the most insidious enemies in sealed display cases.

Test Results (British Museum Protocol)

The accelerated aging test (28 days at 60°C with high RH) confirmed the absolute suitability of the complete product (outer packaging, tyvek, and stabilizing agent):

Final verdict: product suitable for permanent use.

Propadyn Museart can be placed inside display cases, showcases, and archives without any risk of chemical contamination for the contained artworks.
