It is especially useful in systems that are diluted with water prior to use. BENAQUA 4000 provides high viscosity in the low- to medium-shear-rate region. It gives superior sag resistance at low package viscosity compared with conventional thickeners, as well as improved shear-thinning rheology. Textured and stippled effects are enhanced and paints exhibit a richer appearance.
