ABSTRACT:
A novel, pumpable, thermoplastic desiccated mastic capable of desiccating a sealed insulating glass unit. The compositions utilize adhesive materials which have a low vapor transmission rate but, nevertheless, have been found to effectively dry the air space in the unit. They do not contribute to chemical fogging and, in preferred embodiments, reduce or eliminate chemical fogging caused by other structures in the assembly. The compositions adhere well to the U-channel material and do not flow or sag under the normal range of service conditions encountered by an insulating glass assembly.
