Do you know why water-based thickeners improve paint flow? Water-based thickener 2521 delivers excellent open-can performance, enabling a smooth, natural application process during paint use. It reduces the surface tension of the coating system, making the liquid easier to flow. When added to coatings, the water-based thickener immediately alters the rheological properties of the liquid. Through adsorption, dispersion, and polymerization, it imparts ideal viscosity and flow characteristics to the liquid. This makes the coating easier to apply and meets various construction requirements.
