The need for the evaluation of the adhesive bonding systems for the Medical Unit, Self-Contained, Transportable inflatable shelter under extreme environmental temperatures, 94 C (200 F) in the desert and -46 C (-50 F) in the arctic, results from the failures found when new shelters were erected in the field. Some of the observed failures, which would seriously affect the performance of the shelters in the field, could be traced to poor adhesive bonding. It was found that the two adhesives, Bostik 1039/5 and Bostik 1095/9, could be used successfully in bonding seams in MUST shelters for low temperature use. However, the adhesive Bostik 1095/9 is stiffer and more brittle when subjected to low temperatures than the adhesive Bostik 1039/5. This increase in stiffness and brittleness is reflected in MUST shelters by an increase in storage volume and an increased propensity for seam separation when compared with an identical MUST unit made with adhesive Bostik 1039/5.
