Dosage & Directions for Use
The required dosage depends strongly on the type and concentration of foaming agents, process temperature, agitation and contamination level.
Initial recommended dosage
10-100 ppm
for routine foam prevention.
Moderate foam
50-250 ppm
Severe / persistent foam
100-500 ppm
Shock treatment
250-1,000 ppm
For exceptionally severe foam conditions, higher concentrations may be required during initial treatment, followed by a lower maintenance dose.
Recommended practice: Start at the lowest effective dosage and increase progressively.

Product Description & Chemical Profile
RXSOL Antifoam Defoamer AF20 is a concentrated, silicone-free antifoaming agent formulated using a synergistic combination of proprietory alcohols.
The formulation is designed to provide both rapid foam knockdown and sustained foam suppression. Antifoam Defoamer AF20 provides rapid destabilization of foam lamellae, while also contributing to persistent foam control and improved antifoam activity.
RXSOL Antifoam has demonstrated rapid foam-collapse performance in laboratory antifoam testing, including foam collapse within minutes and resistance to re-foaming under agitation/sparging conditions.
