How can we improve flow and leveling in small imperfections and scratches?
The flow and leveling to remove scratches and small defects has been a problem for paint shops since they first applied coatings. Generally, flow and leveling can be improved through rheological modification and the use of surface tension modifiers. If the viscosity is low enough, flow is good; but with increasing viscosity, the flow decreases. However, if the viscosity is too low, sag will be the result.
