Additionally, environmental conditions (%RH) seem to have a significant effect on the degree of plasticization. Increasing %RH allows the BADGE/JeffAmine to retain viscous behavior under the investigated times and rates, while lower %RH seems to help gain a more elastic behavior. In summary, in all unaged cases, we observe mainly cohesive failure. In conditions such as the ones shown in Figure (stiff spring to maintain constant separation distance and smooth alumina surfaces), it could be argued that the failure mode is mixed (cohesive and adhesive). However, it is very unlikely that no precursor film has formed during the early stages of cure.
