|Summary||The climatic exposure experiment of two moderate temperature curing structural adhesives at a hot, wet seacoast weathering site and a cold, dry weathering site are presented in this paper. The unloaded lap-shear joint and floating roller peel joint are employed to indicate the influence of different weathering and different joints. We can summarize that the hot, wet, seacoast weathering brought about deterioration at a far greater rate than the cold, dry weathering did, and the floating roller peel joint was more sensitive to hot, wet, seacoast site than the lap-shear joint was. The remaining strength of indoor lap-shear joint and accelerated aging experiment result were also discussed for comparison.
