X-Air™ LE

Liquid Cement Antifoam



In cementing, foam created during mixing can cause pump cavitation and decrease cement density, consequently impacting the strength of the cement.


Hexion’s X-Air™ LE liquid cement antifoam is designed to prevent air entrainment and control foam in cement systems, improving accuracy of slurry density readings.   The system utilizes a unique chemistry that is more efficient than the competition and applicable in a variety of cement systems.



  • Decreases foam formation in cement systems
  • Effective in systems containing polyvinyl alcohol (PVA)
  • Liquid formulation allows for on-the-fly addition and adjustments
  • Can be used at ambient temperatures less than -40°F                                                                                                                                                                                                                    

LE Chart  

The X-Air LE liquid Cement antifoam is more than five times as effective as the competitor at 0.1%. Even at half the concentration, X-Air LE cement antifoam is still over two and a half times as effective as the competitor.
