The Influence of Curing Temperature on Rheological Properties of Epoxy Adhesives

The curing process of three different epoxy adhesives, which are appropriate for bonding wood with metal, was characterized on the basis of their rheology. The rheological measurements were carried out using a TA Instruments ARES G2 stress control rheometer. The infl uence of temperature on the curi...
