High Adsorbing Molecular Sieve Desiccant for Remove fogging in Dual Pane Windows
Product Description of Molecular Sieve Desiccant
Molecular sieves are used in sealed insulating glass units to prevent fogging. Fogging on inner glass surfaces by condensation of water and solvent vapors is common inside sealed dual pane windows. Window fogging arises when the vapors trapped between the two panes of the insulating glass unit condense on the glass surface. This is due to the lower temperature of the glass surface than the dew point of the air between the two panes.
To prevent fogging the moisture vapor concentration inside the dual-pane window must be controlled. Using this desiccant molecular sieves for insulated glass can absorb moisture more than all commercially available adsorbents and sometimes they also can remove solvent vapors. When moisture or solvent vapors are absorbed by the molecular sieves, the moisture vapor concentration in the air space is reduced and the moisture dew point of the airdrops to a lower value and no condensation can occur until the glass temperature goes below that.
