Diacel® ATF-S Liquid Cement Antifoam Additive is a silicone based liquid antifoaming agent for cement slurries, and it is compatible with all commonly used cement additives.
Add Diacel® ATF-S Liquid Cement Antifoam Additive to all cement slurries for the prevention of air entrapment in the slurry during mixing. Air entrapment can result in several mixing problems. In extreme cases of air entrapment, transfer pump cavitation may occur. More commonly, air entrapment will cause the slurry density to appear lower than desired when determined by common density-measuring devices. Increasing the actual slurry density to account for the apparent deficit causes negative effects. These effects include an increase in the slurry viscosity, reduction in the slurry volume, and reduction of the thickening time.
