Our powder Air Entrainer is a high-purity Sodium Alpha-Olefin Sulfonate solid surfactant for dry mortar and cast-in-place concrete. It creates evenly distributed closed microbubbles to maintain 4%-7% air content, acting as stress relief chambers to resist freeze-thaw damage and deicing salt scaling.

Powder Air-Entraining Admixture, a pale yellow powder, features hard water tolerance, high biodegradability, and great compatibility with polycarboxylate superplasticizers. It improves workability while reducing bleeding, segregation and honeycomb defects. Free of liquid leakage, it simplifies storage and feeding. Ideal for masonry mortar, self-leveling plaster, roads, bridges and hydraulic projects. We offer 25 kg bags, custom formulas, and OEM for global concrete and dry mortar manufacturers.
