What is Defoamer?

Defoamer is a functional admixture designed to control and eliminate foam in water-based systems such as concrete, mortar, coatings, and industrial processes. By rapidly breaking bubbles and preventing their re-formation, it ensures a smoother mixture and more stable material properties.

The use of Defoamer delivers multiple benefits: reduced air content, improved surface quality, enhanced strength development, and higher material density. It helps prevent defects such as voids, pinholes, or reduced durability caused by excessive entrapped air.

For demanding construction and industrial applications, Defoamer ensures consistent performance, better finishing, and reliable long-term quality—making it a vital additive across various formulations.

Advantages

The surface is uniform and delicate, and it has good adaptability to changes in ambient temperature.
