Rheology

• Rheology is important to control workability, flow and sag resistance of a coating

• Rheological properties can be adjusted according to the usage area of the coating (e.g. airless spray application, brush and roller application etc.)

• The rheology profile in Hardtop One has been carefully tuned to be brush and roller friendly
