Paint rheology

Paint materials vary by by their major designed components (binder, diluent, filler and additives) as well as from batch to batch. From paint manufacture to finished painted article, the fluid can go through a large range of of deformation rates, as well as experiencing different kinds of flow. This makes understanding and controlling the rheology of paints a desirable subject.

DrRheology can support paint manufacturers and paint users by testing the paint, as well as calculating flow performance. The key tests offered below will allow product and process development, as well as supplying spot checks for QC.
