SAG RESISTANCE VS LEVELL ING
bull Finding a balance between sagging and levelling can be challenging
bull Sagging is driven by the gravitational shear stress
bull Levelling is mainly driven by the surface tension
bull Sagging can be reduced by increasing the viscosity of the paint at low shear rate or by applying thinner coatsbull No sagging will occur unless the gravitational shear stress exceeds the yield stress
bull Viscosity of 25-50 Pas at low shear after application is sufficient
bull Levelling can be accelerated by lowering viscosity increasing surface tension or by applying thicker film bull Increasing surface tension and thicker film are usually not favored options

bull Sagging is driven by the gravitational shear stress
bull Levelling is mainly driven by the surface tension
bull Sagging can be reduced by increasing the viscosity of the paint at low shear rate or by applying thinner coatsbull No sagging will occur unless the gravitational shear stress exceeds the yield stress
bull Viscosity of 25-50 Pas at low shear after application is sufficient
bull Levelling can be accelerated by lowering viscosity increasing surface tension or by applying thicker film bull Increasing surface tension and thicker film are usually not favored options
