摘要：

Adhesive joints consisting of glass bonded to lead alloy with an epoxide adhesive have been aged at 5-degrees-C at relative humidities of 50 and 100% for up to 3 months. In some joints the glass had been pretreated with a silane coupling agent. Joints aged at 50% relative humidity show no weakening, and at 100% joints with silane pretreatment are not weakened as much as those without it; many of the latter samples fell apart during ageing. The diffusion coefficient of water in the adhesive has been obtained from an absorption experiment. The rate at which joints are weakened is higher than can be accounted for by diffusion of water in the adhesive. Water is supplied to intact regions of the adhesive bond by way of zones that have been disbonded.
