FoamStar® PB 2922 is a highly effective defoamer or air-release agent particularly suitable for use in powder-based emulsion paints and in similar formulations. FoamStar® PB 2922 can be mixed with all other powder components without any problems. It yields particularly good
results in the manufacture of powder-based leveling compounds and mortars as well as plasters based on cement.

In these cases, the use of FoamStar® PB 2922 ensures a fast escape of air entrapped while incorporating water. The resulting mastics have a smaller content of air pores and show a smooth and bubble-free flow.
