Product Code: RXSOL-81-2066-200
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.
The required dosage depends strongly on the type and concentration of foaming agents, process temperature, agitation and contamination level.
10-100 ppm
for routine foam prevention.
50-250 ppm
100-500 ppm
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.

Mode of Action of FOAM KNOCKDOWN
The hydrophobic alcohol components migrate toward the air-liquid interface and interfere with the surfactant film surrounding the foam bubble.
The antifoam disturbs the elastic surfactant layer, promoting thinning and rupture of the bubble wall.
Antifoam AF20 provides rapid foam-breaking activity. Published testing has demonstrated rapid collapse of foam following addition of Antifoam AF20 .
Antifoam AF 20 with its longer hydrocarbon chain, contributes to a more persistent hydrophobic phase that can remain active during continued agitation.
The combination is intended to reduce the tendency of foam to regenerate after agitation, pumping, aeration or circulation.
