BYK 051N is a silicone-free defoamer on polymer-basis that provides excellent compatibility with solvent-borne systems. It offers superior defoaming properties for applications requiring transparency and bubble-free finishes. BYK 051N effectively destroys foam in polar solvent systems without negatively impacting appearance or causing defects. As a specialized additive, BYK 051N supports optimized processing by ensuring uniform dispersion and bubble-free results. Its high compatibility allows formulating transparent finishes even at higher dosage levels. BYK 051N is particularly suitable for applications where bubble-free, transparent finishes are required to meet aesthetic and performance needs.
