This phenomenon appears only on the edge of the adhesive because the duration of the ageing treatment was too short to allow a uniform diffusion of water in the entire adhesive. Figure7 : DSC results from EA 9309NA unaged specimen. Figure 8 : DSC results from EA 9309NA specimen aged in air. The specimens aged in salt water showed an intermediate behavior between those aged in distilled water and those aged in the air. This result may be due to a greater difficulty of salt water to penetrate into the adhesive.
