Unlike common silica gel — which merely absorbs — Propadyn Museart stabilizes relative humidity at a precise percentage, between 35% and 80%, set prior to delivery: it arrives ready for use, with no pre-conditioning required.

It absorbs and releases moisture rapidly, with a resolution of 3%, maintaining a constant value even as the surrounding environment fluctuates — in the display case, the crate or the packaging, over extended periods and without electrical power.
