Antifoam Defoamer AF20

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.

Notes

Key Features of RXSOL Oil and Gas ANTIFOAM

• Silicone-free foam control
• Rapid foam knockdown
• Long-lasting antifoaming action
• Effective under agitation and aeration

Precautions

Mode of Action of FOAM KNOCKDOWN

Foam Film Destabilization

The hydrophobic alcohol components migrate toward the air-liquid interface and interfere with the surfactant film surrounding the foam bubble.

Reduction of Foam Film Stability

The antifoam disturbs the elastic surfactant layer, promoting thinning and rupture of the bubble wall.

Rapid Bubble Collapse

Antifoam AF20 provides rapid foam-breaking activity. Published testing has demonstrated rapid collapse of foam following addition of Antifoam AF20 .

Persistent Foam Suppression

Antifoam AF 20 with its longer hydrocarbon chain, contributes to a more persistent hydrophobic phase that can remain active during continued agitation.

Re-Foaming Control

The combination is intended to reduce the tendency of foam to regenerate after agitation, pumping, aeration or circulation.

Useful area

• Silicone-free formulation
• No silicone carryover
• Suitable for systems where silicone contamination is undesirable
• Organic alcohol-based chemistry
• Rapid foam knockdown
• Good compatibility with many aqueous chemical systems
• Easy incorporation into process formulations
• Suitable for continuous or intermittent dosing

Industrial area

What causes foam in aqueous systems like desalination plants?

• Algae and plankton
• Organic decomposition products
• Hydrocarbon contamination
• Biological activity
• Turbulent mixing and aeration

Quick foam knockdown plus extended foam prevention properties in RXSOL Antifoam AF10

• Batch processes
• Cleaning tanks
• Wastewater tanks
• Reaction vessels
• Mixing vessels

• Stop or reduce the foam-generating operation if possible.
• Apply a small quantity of antifoam directly onto the foam.
• Allow approximately 1–5 minutes for foam collapse.
• Restart circulation/aeration.
• Establish a lower continuous maintenance dose if required.
