It is a 25% solution designed for use in conventional water-based system.


It is rheological additive. Excellent rheology improves medium-shear range viscosity enhances film build, improves flow and leveling, develops pH-independent rheology easily incorporated compatibility.


The typical quantity of WPU-26-T25F is 0.1 to 1.0% by weight of the water-based systems. To achieve optimum properties, the system’s surfactant blend may need modification.
