FOAMSTAB FS 730
12% active fluorosilicone defoamer for systems demanding extremely fast foam knockdown and superior surface levelling in premium solvent-borne coatings.
Key Performance Benefits
-
Extreme Foam Knockdown Speed
The higher 12% active fluorosilicone concentration rapidly collapses severe macrofoam generated during aggressive dispersion and high-pressure pumping operations. -
Superior Surface Leveling
Functions as an effective leveling agent, minimizing orange peel, pinholes, craters, and surface popping in high-gloss coating systems. -
Ultra-Low Surface Tension Action
Delivers outstanding foam control in difficult resin formulations containing aggressive polar and aromatic organic solvent blends. -
High-Temperature & Chemical Stability
Maintains excellent de-aeration efficiency in bake enamels, coil coatings, and chemically resistant industrial lining systems.
Recommended Applications
-
Premium Automotive OEM & Refinish
High-solids clearcoats, metallic basecoats, and premium topcoats requiring exceptional distinctness of image (DOI). -
High-Performance Industrial Finishes
Solvent-borne polyurethane, epoxy, and fluoropolymer protective coating systems. -
Coil & Container Coatings
Fast-curing, high-speed roll-applied industrial lacquers and continuous coil coating applications. -
Specialty Solvent Systems
High-viscosity resin formulations utilizing challenging aromatic and ester solvent blends for demanding industrial applications.

Dosage & Processing Guidelines
Due to the boosted 12% active fluorosilicone concentration, the recommended addition level for FOAMSTAB FS 730 is 0.02% to 0.3% based on the total formulation weight.
-
Grind / Let-Down Phase
Can be incorporated during the initial resin and pigment grinding stage or post-added during the let-down phase under medium agitation. -
Pre-Dilution
Pre-diluting in a portion of the formulation solvent before addition promotes rapid, uniform incorporation, especially in sensitive clearcoat formulations. -
Optimization
Perform ladder testing beginning at 0.05% to establish the minimum effective dosage for defect-free surface leveling and foam control.
At a 12% active level, FOAMSTAB FS 730 delivers concentrated fluorosilicone power for high-speed industrial lines (such as coil coatings or automated spray booths). It targets two formulation challenges at once: popping microbubbles during flash-off and reducing surface tension gradients to ensure flat, flawless leveling without causing fish-eyes.
