Joints consisting of glass bonded with polysulfide sealants have been aged at 95% relative humidity and 60-degrees-C for up to 14 months. All were weakened and some with higher levels of plasticizer fell apart during exposure. The amount of interfacial failure increased with exposure, and was related to a discolouration which develops in the sealant and can be seen through the glass. The rate of joint weakening is greater than can be accounted for by the rate at which water diffuses into the sealant. Thermodynamic predictions based on measurements of contact angles show that the bonds are probably unstable in the presence of water.
