Fast foam knockdown + microbubble release for smoother, defect-free films
FOAMSTAB 830 is a high-performance defoamer and deaeration additive supplied as a 10% active formulation, developed for demanding industrial systems where foam and entrained air cause surface defects, processing instability, and productivity losses. It is designed to deliver rapid foam knockdown, long-lasting foam control, and improved air-release during high-shear mixing, circulation, spray application, or high-speed dispersion.
In coating and process formulations, FOAMSTAB 830 helps achieve uniform, defect-free films by reducing microfoam, pinholes, craters, and entrapped air voids. The 10% active format enables controlled dosing and easier handling while still offering strong performance at low addition levels. FOAMSTAB 830 is particularly useful in systems that foam due to wetting agents, dispersants, surfactants, or mechanical agitation, where consistent film appearance and performance are critical.
FOAMSTAB 830 supports smoother surfaces and better levelling by minimizing bubble-related disruptions at the coating surface. It can be used in a wide range of formulations including industrial coatings, water-based systems, process chemicals, and specialty functional coatings, depending on compatibility requirements. Overall, FOAMSTAB 830 is positioned as a reliable, high-efficiency defoaming solution for modern formulations that demand clean appearance, stable processing, and low defect levels.

Controls foam during dispersion and application, reducing craters, pinholes, microbubbles, and improving coating appearance and consistency.
Provides foam knockdown and deaeration in systems prone to foam due to surfactants, dispersants, and high-speed mixing.
Reduces foam in spray, circulation, and agitation processes, improving stability and reducing overflow or foam-related downtime.
Helps release entrapped air and stabilize processing, supporting smooth films and consistent application behaviour (system dependent).
Helps manage foam in formulations using wetting/dispersing additives where conventional antifoams may be insufficient.

Quickly collapses foam and maintains control under continued agitation, circulation, and shear.
Minimizes craters, pinholes, microfoam, and bubble-related surface defects—supporting improved finish quality.
Helps remove entrained air during mixing and application, reducing voids and improving film continuity.
By reducing microbubbles at the surface, it supports smoother films and more uniform appearance.
10% active form supports accurate dosing and consistent performance with minimal disruption to formulation balance.
Treat as an industrial specialty chemical. Avoid inhalation of mist and avoid contact with skin and eyes. Use in well-ventilated areas.
Safety goggles/face shield, chemical-resistant gloves (nitrile), and protective clothing. Use respiratory protection where spray mist is generated.
Skin contact: Wash with soap and water; remove contaminated clothing.
Eye contact: Rinse with water for several minutes; seek medical attention if irritation persists.
Inhalation: Move to fresh air; seek medical advice if symptoms occur.
Ingestion: Rinse mouth; do not induce vomiting; seek medical attention.
Fire & decomposition – Use foam, dry chemical or CO₂ extinguishers; overheating may release irritating fumes; use SCBA in a fire situation.
Environmental precautions – Prevent release to drains and water bodies. Contain spills with inert absorbent and dispose per local regulations and the official SDS.
