摘要

All coatings processes have an abrupt short duration shear region that controls the application process. Measurements of the force required to make an abrupt increase in shear rate has forecast performance in a variety of applications. Further the valves are the same for a satisfactory process conditions independent of the chemistry used. This force is related to both the chemical associations that break down under shear and the occupied volume of a coating. This paper describes simple approximations of the process shear rate for a variety of coating methods and reviews case studies where rheology data has solved operating problems. It provides techniques and guidelines for dispersing pigments, eliminating rheology scratches, and the viscous influence on coat weight and leveling. Surface tension and elastic forces also influence leveling. Indexes for these properties are presented as well as useful values for the process.
