Zeolan-K is a high-performance molecular sieve desiccant designed for insulating glass unit (IGU) production in accordance with EN 1279 standards.
The material is engineered to adsorb moisture and maintain a dry internal environment inside the glass unit, ensuring long-term performance and preventing condensation. Due to its controlled pore structure, Zeolan-K effectively absorbs water vapour while limiting adsorption of insulating gases such as argon, helping to preserve thermal efficiency.
MAIN PROPERTIES
✔ High moisture adsorption capacity
✔ Controlled adsorption selectivity (water vs. gas)
