Adsorbents for insulating glass: see-through reliability

Your entire shipment of windows is returned. The slight fog between the panes of insulating glass has cost you an entire production run that you can’t afford to lose. This is every window manufacturer’s nightmare.

You can avoid increased unit stresses and loss of insulating properties with UOP’s molecular sieve adsorbents. Developed for residential and commercial sealed insulating glass, we have the most reliable, effective way to adsorb water and organic solvents within your dual pane windows. Using our adsorbents can keep your windows in the clear.

High capacity UOP MOLSIV™ adsorbents remove and trap water and solvents, maximizing the life of your units. We have a variety of products for different systems and needs:

  • Window systems with metal spacers
  • Units with a desiccant matrix or polymer spacer
  • Systems that require both water and organic vapor removal
  • Solvent-free systems

Contact us to understand which solutions will work best for you.

In addition to superior adsorbent products, we offer a comprehensive MOLSIV Insulating Glass Engineering Services software program. This service can help you evaluate the cost, insulating properties, and deflection and stress characteristics of insulating glass units for a wide range of designs, dimensions, gas filling options and exposure conditions.
