Key Performance Benefits

  • Hybrid Synergy
    Combines the immediate foam knockdown capability of organo-modified silicones with the long-term foam suppression stability of organic polymers.
  • Broad System Compatibility
    Highly reliable in solvent-borne, high-solids, and 100% solvent-free resin environments.
  • Defect Reduction
    Efficiently releases entrapped microfoam to minimize pinholes, surface voids, and craters during high-shear mixing or spraying.
  • Persistent Performance
    Maintains defoaming efficiency during prolonged storage and extended shelf-life periods.

Recommended Applications

  • Industrial Coatings
    Solvent-borne protective coatings, machinery finishes, and OEM lacquers.
  • Epoxy & PU Flooring
    Solvent-free 2K epoxy self-leveling floors and polyurethane screeds.
  • Printing Inks & Varnishes
    Solvent-based flexographic and gravure printing ink formulations.
  • High-Solids Systems
    Resin-rich clearcoats, primers, and high-performance binder systems.

Dosage & Processing Guidelines

The recommended dosage range for FOAMSTAB 141 is 0.1% to 0.5% based on the total formulation weight.

  • Incorporation Stage
    Can be incorporated during the mill-base (grind stage) or added during the let-down phase.
  • Shear Requirements
    Requires sufficient shear during mixing to ensure homogeneous distribution throughout the formulation.
  • Formulation Tip
    For sensitive clear coat systems, conduct transparency and leveling tests before full-scale production.

💡 Formulator Insight & Lab Tip

Silicone-polymer hybrid additives such as FOAMSTAB 141 eliminate the traditional compromise between rapid foam knockdown and long-term foam suppression. The silicone component provides instant surface defoaming during high-speed dispersion, while the polymeric backbone continuously releases entrapped microfoam during high-build spray application, roller coating, or doctor-blade coating. This unique hybrid mechanism delivers superior surface finish, minimizes coating defects, and maintains consistent performance throughout the application process.
