Drykeeper Technical Datasheet

Product name: Drykeeper

Product features

• A rubber sheet blended with a reversible, water‑absorbing polymer that captures moisture at high humidity and releases it when humidity drops.
• Because the polymer regenerates its absorption capacity automatically, the product operates without maintenance.
• Compared to silica gel, it offers significantly higher moisture absorption while maintaining a long service life.

Main applications

• Prevention of condensation inside enclosed spaces such as control panels.
• Reduction of fogging caused by condensation inside surveillance cameras.
