Abstract

The effects of exposure of polysulfide aircraft sealants to air, moisture and extremes cf temperature (together with various combinations of these conditions) are reviewed with reference to the cured sealants, the mixtures during cure and the stored sealant components. In order to properly understand the reasons for property changes resulting from exposure to these effects, the underlying chemical processes must be identified. This in turn requires detailed knowledge of the composition of the sealant formulations and of the reactive sites in the polymer backbone. Examples will be given in which the environmental resistance of polysulfides can be rationalized in these terms.
