Key Performance Benefits

  • Full-Lifecycle Foam Suppression
    Effectively controls foam throughout grinding, mixing, high-speed filling, and final application by roller, brush, or spray.
  • Excellent Persistent Defoaming
    Delivers long-lasting anti-foam performance during extended storage while maintaining consistent defoaming efficiency.
  • Cost-Effective Efficiency
    High active performance at low dosage levels makes it ideal for commercial architectural paints and large-scale production.
  • Easy Dispersion & Compatibility
    Disperses smoothly into waterborne binder systems without causing fisheyes, oil separation, or other surface defects.

Recommended Applications

  • Architectural Paints
    Interior and exterior water-based emulsion paints including styrene-acrylic, PVA, and pure acrylic formulations.
  • Construction Primers & Wall Putties
    High-PVC primers, masonry coatings, wall putties, distempers, and related construction coating systems.
  • Polymer Emulsions
    Water-based binders, latex dispersions, polymer emulsions, and construction chemical formulations.
  • General Industrial Aqueous Finishes
    Water-reducible industrial coatings, trade paints, and economical water-based finishing systems.

Dosage & Processing Guidelines

The recommended dosage for FOAMSTAB WBA is 0.1% to 0.5% calculated on the total formulation weight.

  • Split Incorporation
    For optimum performance, add 50% during pigment grinding/dispersing and the remaining 50% during the let-down phase.
  • High-Shear Dispersion
    High-shear mixing ensures hydrophobic particles are uniformly distributed throughout the aqueous binder matrix for maximum foam control.
  • Ladder Testing
    Perform a dosage series to determine the minimum effective concentration based on filler loading, surfactant level, and formulation requirements.

In water-based architectural coatings and emulsion paints, air incorporation during high-speed dispersion and pumping can lead to volume loss and surface micro-pinholes upon roller application. FOAMSTAB WBA utilizes a synergized mineral oil and hydrophobic particle matrix to destabilize foam cell walls rapidly, maintaining steady density during packaging and smooth application.
