This indicates that Timberset has high cross-linkdensity and that might hinder water diffusion. This result issupported by other studies. In authors’ previous work onmoisture uptake studies for all the adhesives (Ahmad et al. explained by only in terms of water as plasticizing effect.The free volume and the epoxy-water interactions couldbe used to explain the behaviour observed. Pethrick et al.the network and bound water in strong interactions withpolar segments.The rupture of the interchain hydrogen bonding bywater molecule would produce an increment of the chainmobility and hence a reduction in the effective crosslinkdensity of the material (Nogueira et albe expected. Thus, the stronger the water-polymergreater the reductions in E’ and T g values. Therefore in stronger than Albipox and Timberset which results in higherT g value. The superior water uptake48
