Foamstab 141 is a high-performance silicone–polymer hybrid defoamer engineered to deliver fast, reliable, and long-lasting foam control in solvent-borne and solvent-free systems.
Designed for demanding industrial formulations, it provides exceptional efficiency in coatings, adhesives, sealants, and polyurethane thermosets where microfoam, air entrapment, and surface defects are common challenges. Its unique blend of foam-destroying polymers and polysiloxanes ensures superior defoaming during both manufacturing and application stages.
Foamstab 141 helps achieve smooth film appearance, improved gloss, better clarity, and reduced pinholes or craters even in high-solids and high-viscosity systems.
It is highly effective across a wide range of resin chemistries, making it a versatile solution for formulators. With its low dosage requirement and strong air-release properties, Foamstab 141 enhances productivity and process stability. Whether used in millbases, resin systems, or finished formulations, Foamstab 141 ensures consistent, defect-free results and superior overall performance.
Anti-foam additive, high-efficiency defoamer and de-aerating agent designed for solvent-borne and solvent-free coating systems, adhesives, sealants, and polyurethane thermosets.

Instantly eliminates surface foam and entrapped air during manufacturing and application.
Prevents microbubbles, pinholes, and crater formation in high-solids and high-viscosity systems.
Enhances clarity, gloss, smoothness, and overall finish quality in coatings and resin systems.
Effective across PU, epoxy, alkyd, acrylic, polyester, and solvent-free or solvent-borne formulations.
Enables consistent mixing, better flow, and uniform surface quality with reduced defects.
Delivers strong defoaming action even at very low addition levels, making it cost-effective.
Minimises foam generated during spraying, brushing, roller application, and casting.
Works effectively in high-shear dispersion and manufacturing environments.
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.
