BYK Defoamer

The BYK defoamer series delivers tailored foam suppression for solvent-based, aqueous, and solvent-free formulations across coatings, adhesives, and industrial processes. Combining hydrophobic polymers and silicone-free or silicone-enhanced chemistries, these agents rapidly collapse surface foam while preventing re-entrainment in high-viscosity or shear-sensitive systems.

Engineered for compatibility with epoxy, polyurethane, and emulsion-based resins, the series minimizes defects like pinholes or craters in high-gloss coatings and adhesive layers. Their low-dosage efficiency ensures stable viscosity control in pigment-rich or high-solid systems, enhancing production throughput and surface quality.
