Alginate should be poured immediately as it is subject to deformation, which can include imbibition, an uptake of water that results in swelling, or syneresis, a loss of water that results in shrinkage (Rohanian et al. Although this process of bond interchange and that of continued polymerization during deformation may be contributory mechanisms to permanent set, bond rupture appears to be the primary mechanism.
