Defoamer is a specialized high-efficiency additive designed to eliminate and prevent the formation of unwanted air bubbles during the mixing and application of building materials. In the dry-mix mortar industry, it is typically supplied in a stable powder form, consisting of active defoaming agents (such as hydrocarbons, fatty acids, or silicone-based compounds) adsorbed onto an inorganic carrier.

In cement-based and gypsum-based systems—such as self-leveling floor compounds, high-strength grouts, and waterproof mortars—Defoamer plays a critical role in optimizing the density and integrity of the material. By rapidly breaking down macro-bubbles and preventing the stabilization of micro-foam, it ensures a smooth, crater-free surface finish. This removal of trapped air is essential not only for the aesthetic quality of the surface but also for the mechanical performance, as excessive air voids can significantly reduce the final compressive and flexural strength of the hardened product.

Our powder defoamers are engineered for excellent stability and long-term effectiveness. They disperse quickly and evenly upon the addition of water, providing immediate foam-breaking action without compromising the performance of other chemical additives like RDP or cellulose ethers.

Key Performance Attributes:

• Rapid Defoaming: Quickly eliminates air bubbles generated during high-speed mixing.

• Surface Perfection: Prevents “pinholes,” craters, and surface irregularities in self-leveling and coating applications.

• Strength Optimization: Increases the density of the mortar, leading to higher compressive and bonding strength.

• High Stability: Maintains its effectiveness throughout the shelf life of the dry-mix and during prolonged application periods.

• Excellent Compatibility: Does not interfere with the hydration process or the water-retention properties of the system.
