New literature from Grace Davison, a unit of W.R. Grace & Co.-Conn., explains the benefits of PHONOSORB 802 LD® desiccant for solving glass deflection problems associated with insulating glass units. This product bulletin defines the problems associated with glass deflection, describes benefits of PHONOSORB 802 LD in eliminating nitrogen gas adsorption and minimizing glass deflection, and offers product performance data.

The increased use of internal muntin bars in insulating glass units has resulted in a lower tolerance than ever for glass deflection which causes increased seal stress and failure, glass breakage at low temperatures, loss of insulating value, and distorted reflected images. PHONOSORB 802 LD eliminates nitrogen gas adsorption by replacing harmful 13X molecular sieves used for chemical vapor adsorption, resulting in insulating glass units that last longer, look better, and retain their insulating value.
