Thermo-mechanical properties of white oil and acrylic artist paints

To efficiently summarise mechanical data, the time-temperature superposition (TTS) principle was used to construct master-curves of secant modulus and failure strain as a function of strain rate. Comparisons are given between films tested within this study, and also with individual data points for oil paints obtained from literature. The findings highlight the differences between artist paint media over a broad time-scale, and practical temperature range. A simple estimate of dynamic failure criteria is also presented using a first order approximation.
