Rheology of high solid coatings. II. Analysis of combined sagging and leveling

摘要

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‐1of about 50 poises. This theoretical prediction is confirmed experimen
