Foamstab 2722 is a high-efficiency defoamer and de-aeration additive specially developed for solvent-free and high-build epoxy, polyurethane, and unsaturated polyester systems.
Built using an advanced mixture of silicone and silica particles, it delivers extremely rapid air release, strong foam suppression, and exceptional surface smoothness even in highly reactive resin systems. With an active content of > 90%, Foamstab 2722 provides powerful defoaming at low dosage, making it ideal for heavy-duty industrial, flooring, casting, and self-leveling applications.
Its unique silicone–silica synergy ensures efficient bubble breakup while maintaining excellent compatibility and preventing surface defects such as pinholes, craters, and popping. Foamstab 2722 also provides auxiliary leveling benefits, helping achieve uniform, defect-free films in thick-layer coatings. This makes it a reliable choice for formulators working with modern high-solids, solvent-free, and fast-curing systems requiring strong de-aeration performance.
Anti-foam additive, high-efficiency defoamer and strong de-aerating agent for epoxy, polyurethane, UPE, and solvent-free resin systems.

FOAMSTAB 520 is a polymer-based, silicone-free defoamer formulated in a hydrocarbon solvent system with a low flash point, and must be handled as a flammable liquid.
Vapors may form flammable mixtures with air near heat or ignition sources.
Prolonged or repeated exposure may cause mild skin or eye irritation.
Use only in well-ventilated areas to avoid inhalation of vapors or aerosol mist.
Avoid direct contact with skin and eyes; wear protective gloves, goggles, and suitable clothing.
Do not smoke, eat, or drink while handling the product.
Ensure proper grounding and bonding when transferring material to prevent static discharge.
Always keep the container tightly closed after use.
Store in a cool, dry, and well-ventilated area, away from heat, sparks, open flames, and other ignition sources.
At low temperatures, FOAMSTAB 520 may show slight turbidity or separation; warm gently to ~40 °C and mix well before use.
Protect from direct sunlight and store in original, properly labeled containers.
Inhalation: Move affected person to fresh air and keep comfortable. Seek medical attention if symptoms appear.
Skin Contact: Wash thoroughly with soap and water. Remove contaminated clothing. Seek medical attention if irritation develops.
Eye Contact: Rinse with clean water for several minutes. Remove contact lenses if present. Seek medical assistance if irritation persists.
Ingestion: Do not induce vomiting. Rinse mouth and seek immediate medical attention.
Use foam, CO₂, dry chemical, or water spray to extinguish.
Burning may produce irritating fumes and combustion gases.
Firefighters should wear full protective gear and self-contained breathing apparatus (SCBA).
Eliminate ignition sources and ensure good ventilation.
Absorb spilled material with inert absorbents (sand, diatomaceous earth, universal absorbent).
Collect residues in suitable containers for disposal as per local regulations.
Prevent contamination of drains, surface water, or soil.
Avoid uncontrolled release into the environment.
Dispose of waste material, absorbents, and containers strictly in accordance with local disposal rules.
FOAMSTAB 520 is supplied as a technical-grade industrial chemical and is not intended for food-contact applications.
Store FOAMSTAB 520 in a cool, dry, and well-ventilated area, away from direct sunlight and heat sources.
Keep containers tightly closed when not in use to prevent contamination and solvent loss.
Avoid storing near sparks, open flames, or ignition sources, as the product contains a low-flash hydrocarbon solvent.
If stored below 0 °C, the product may exhibit slight turbidity or separation.
To restore full uniformity, warm gently to approx. 40 °C and stir well before use.
Do not expose sealed containers to temperatures above 45–50 °C to prevent pressure build-up.
Ensure adequate ventilation during use to avoid inhalation of vapors.
Wear appropriate PPE, including gloves, goggles, and protective clothing.
Do not eat, drink, or smoke while handling the product.
Avoid splashing or high-speed addition to prevent localized over-foaming or crater formation.
Use only the original, properly labeled containers supplied by the manufacturer.
Ensure drums and containers are always grounded and bonded during transfer to prevent static discharge.
Use pump or controlled pour methods—avoid rough handling or dropping containers.
Keep away from strong oxidizing agents, acids, and alkalis.
FOAMSTAB 520 remains stable for at least 12 months under recommended storage conditions.
Re-homogenize gently if stored for a long time.
In case of small spills, absorb with inert absorbents like sand or universal absorbent.
Collect the absorbed material into suitable containers for disposal as per local regulations.
Avoid letting the product enter drains, soil, or natural water bodies.
Keep suitable extinguishing media nearby: foam, CO₂, dry powder, or water spray.
Ensure fire protection systems are in place for storage areas containing flammable liquids.
FOAMSTAB 520 is an industrial-grade additive and must not be used in food-contact applications.
Follow all applicable local safety, environmental, and storage regulations.
Ideal for laboratory use, small batch production, and formulation trials.
Suitable for medium-scale users and consistent monthly consumption.
