Features Of BASF Efka SI2722 Defoamer

Highly effective silicone-based defoamer for rapid foam knock-down in demanding aqueous systems.
Excellent compatibility and stability in waterborne coatings, adhesives, and industrial cleaning formulations.
Low dosage efficiency—effective at 0.1–0.5 wt% active in most applications.
Minimal impact on gloss, transparency, and substrate wetting performance.
Resistant to shear degradation and stable across a broad pH range (pH 4–12).

Typical Applications Of BASF Efka SI2722 Defoamer

Waterborne architectural and industrial coatings (e.g., acrylic, PUD, epoxy dispersions).
Adhesives and sealants—including pressure-sensitive adhesives (PSA) and construction sealants.
Industrial and institutional (I&I) cleaning agents and detergent formulations.
Printing inks—especially flexographic and gravure inks based on water or low-VOC solvents.
Textile auxiliaries such as dyeing and finishing baths where persistent foam interferes with processing.
