“…Inorganic pigments also tend to be much stiffer than the binding media, also leading to a significant increase in the stiffness of the sample. Many of the studies focused on the effects of temperature [18,29,30,36,37,41,43,46,50,54,57] and relative humidity [15,29,30,34,36,37,41,43,44,46,52,57,59] on the stiffness of the sample. There is a general trend across all three binding media classes of increasing stiffness as the temperature of a paint decreases, shown in Fig.…”
