FoamStar® PB 2941 (formerly Foamaster® PD 1) is a defoamer and anti-foaming agent in powder form for cement and concrete products, formulations based on polyvinyl acetate, polyvinyl alcohol, casein, soya protein, wheaten flour and dextrin. It can be easily mixed with all components of coatings and adhesives in powder form, preferably in formulations based on polyvinyl acetate, polyvinyl alcohol, casein, soya protein, wheat flour and dextrin. Dry blends containing FoamStar® PB 2941 wet faster and more uniformly. Entrapped air, causing problems in pumping, troweling and obtaining a complete cavity fill, is eliminated, thus preventing excessive shrinkage, porosity and other disadvantages of the applied cement or concrete. Further, impermeability is improved.
