The dynamic shear storage and loss moduli G' and G" of the waterborne zinc-rich coating and its binder, a sodium silicate
solution, were recorded with variations of temperature and angular frequency. Results show that G' and G" initially decrease
to minimum and then start to increase, while temperature ramping from 5 to 95°C. However, both the zinc-rich coating and
its binder are not rheologically simple materials. |
