Abstract
Abstract Dielectric spectroscopy (DS) is shown to be a most useful tool for the study of the surface initiated redox cure in model anaerobic acrylic adhesives. These models are deliberately designed to exhibit different levels of cure heterogeneity. The cure is initiated by the surfaces of two substrates on either side of a bondline. The heterogeneous cure situation is referred to as low cure through volume (CTV). Poor CTV is an undesirable feature that leads to mechanical weakness in an adhesive bond. Thus, experimental techniques based on DS are developed to investigate the cure characteristics and in particular the CTV phenomenon in the model anaerobic adhesives.
