Efficient Air Removal
Our defoamers rapidly eliminate entrapped air and surface foam in concrete mixtures, significantly improving the uniformity and surface finish of the final product. This results in fewer pinholes, honeycombs, and voids in hardened concrete structures.
Enhanced Concrete Strength
By minimizing air bubbles, the density of concrete increases, which contributes to higher compressive and tensile strength. This is especially beneficial for high-performance concrete (HPC) and precast applications where structural integrity is critical.
Improved Workability and Flow
Both silicone and polyether-based defoamers maintain or even enhance the workability of concrete mixtures. They support smoother pumping, easier placement, and better compaction without introducing extra water or affecting water-cement ratio.
Excellent Compatibility
Our defoamers are compatible with most types of concrete admixtures, especially polycarboxylate-based and naphthalene-based water reducers. This ensures stable performance in both basic and advanced concrete formulations.
Wide Application Versatility
Whether in hot or cold climates, ready-mix or precast plants, dry or wet conditions—our products are designed to perform consistently. The silicone type is ideal for high-temperature and long-working-time projects, while polyether types suit rapid production lines.
Environmentally Friendly Options
Polyether-based defoamers are formulated without harsh solvents or VOCs, making them safer for workers and more sustainable for the environment. These green options comply with international environmental standards.
Low Dosage, High Efficiency
With only a small amount (typically 0.1%–0.3%) needed per mix, our defoamers are highly economical. A little goes a long way, making them ideal for large-scale concrete production where cost efficiency matters.
Long-Term Stability and Shelf Life
Thanks to their stable formulations, our defoamers retain their performance even after long periods of storage or under fluctuating temperatures. This ensures reliable results from batch to batch.
