FOAMSTAB WBA
12% active fluorosilicone defoamer for systems demanding extremely fast foam knockdown and superior surface levelling in premium solvent-borne coatings.
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.
