1 The epoxy mixture has cured to a solid state and can be dry sanded and shaped. 2  You should not be able to dent it with your thumbnail. 3  At this point the epoxy has reached about 90% of its ultimate strength, so clamps can be removed.4  It will continue to cure over the next several days at room temperature.he time it takes for this transformation is the cure time. As it cures, the epoxy passes from the liquid state, through a gel state, before it reaches a solid state (Figure 1). As it cures, mixed epoxy pass from a liquid state, through a gel state, to a solid state.
But the population factor in ânaturalâ disasters is not just important in poor countries, as overpopulated/overexposed East Coast areas in the United States learned during Hurricane Sandy. In the United States, infrastructure development is not keeping up with population growth.
Escape from poverty (personal or for relatives staying behind) is a traditional push factor, and the availability of jobs is the related pull factor. Natural disasters can amplify poverty-driven migration flows. Research shows that for middle-income countries, higher temperatures increase emigration rates to urban areas and to other countries.
