Abstract

AbstractThe rheology of combined sagging and leveling of high solid coatings is analyzed in terms of non‐Newtonian power‐law model. The results indicate that, in order to have good leveling, good sag control, and good sprayability at the same time, high solid coatings should have pseudoplastic rheology with power constant of about 0.5 and viscosity at sec‐1 of about 50 poises. This theoretical prediction is confirmed experimentally.
