Dispersible polymer powders are made by first suspending polymer particles (homo- or copolymers) in water and then spray-drying them. This creates round, powder-like agglomerates with a diameter of about 80 to 100 μm.
After this process, mineral anticaking agents are added to produce a dry, free-flowing and storable polymer powder, which is subsequently stored in bags or silos. During the production of cement or gypsum mortar, the dispersible polymer powder is added to the mixing water and stirred until it disperses on its own. The agglomerates then break up and return to their smaller original molecules.
