Thermorheological properties of the waterborne zinc-rich coating from sodium silicate solution

Xiao-Hong Yang, Wei-Ling Zhu, Li-Gai Li

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.
