The terms anti-foam agent and defoamer are often used interchangeably. Strictly speaking, defoamers eliminate existing foam and anti-foamers prevent the formation of further foam. Commonly used agents are insoluble oils, polydimethylsiloxanesandDefoamers - BASF,Defoamers. Surface active additives in the cement slurry can cause foaming, which may result in pump cavitation and loss of suction head during cementing. Additionally, slurry densities can be changed by air entrainment which makes accurate slurry volume calculations impossible. Basopur DF 5 and Basopur DF 9010 F provide outstanding foam control.Defoamer for surface improvement - MC-Bauchemie,Defoamer for surface improvement With our defoamers, you are able to further reduce the air void content of your concrete and create largely non-porous fair-faced concrete surfaces.
