Molecular Sieve for Insulated Glass
Molecular Sieve for Insulated Glass
OozeChem offers premium 3A molecular sieve beads engineered for insulated glass (IG) desiccant applications. Our high performance desiccants effectively adsorb moisture within IG units, preventing fogging, condensation, and thermal stress. By maintaining optimal moisture levels, our molecular sieves enhance the thermal insulation and structural integrity of IG windows, ensuring long term clarity and durability. Available in various bead sizes, our desiccants are suitable for both air filled and gas filled IG units. Serving clients across the UAE, Saudi Arabia, Kuwait, and the broader GCC region, OozeChem is your trusted partner for insulated glass desiccants.
Why Use Molecular Sieve in Insulated Glass?
Insulated glass units (double or triple glazed windows) require desiccant materials in spacer bars to remove residual moisture and prevent condensation or fogging inside the glass cavity. The right desiccant must:
Adsorb water even at low humidity
Survive thermal cycles (expansion/contraction)
Have low dusting and insignificant gas adsorption
Be compatible with IG sealing materials
3A molecular sieve beads are uniquely suited for this application, due to their pore size (~3 Å) and potassium based ion form, which preferentially adsorb water molecules while excluding larger gas molecules.
How Molecular sieves Works IG Systems?
Bead Insertion & Spacer Filling
Molecular sieve beads are placed within the spacer bar or filler channel between glass panes.Moisture Adsorption
Over time, residual moisture inside the glass cavity or diffusion ingress is adsorbed by the sieve, maintaining a dry, dew point environment.Thermal Cycling Stability
As the glass expands and contracts with temperature changes, the beads maintain integrity and low dust generation.Longevity & Performance
With proper bead selection and activation level, the desiccant remains effective for years under typical conditions.
