Temperature dependence of the viscosity of epoxy acrylate-tripropylene glycol diacrylate binary mixtures

Abstract

AbstractEpoxy acrylate (EA) and tripropylene glycol diacrylate (TPGDA) are two main components of ultraviolet-curable coatings. In this study, the viscosity of EA-TPGDA binary mixtures at various mass ratios was measured by a rotational viscometer at temperatures between 298.15 and 313.15 K. The temperature dependence of the viscosity of the mixtures is discussed. An empirical correlation between the viscosity and the temperature was obtained based on the Andrade equation. The results indicated that the calculated viscosity values show a good agreement with experimental data. This will contribute to the evaluation of the rheological properties and provide a theoretical basis for the industrial application of coatings.
