PFAS-Free Defoamers: Sustainable, High-Performance Solutions for Modern Coating Applications
With rising concerns over per- and polyfluoroalkyl substances (PFAS), industries are moving rapidly towards safer, sustainable alternatives. PFAS, traditionally used for their effectiveness in defoaming and surface performance, are now under global scrutiny due to potential health and environmental risks.
In response, BYK has developed an innovative range of PFAS-free, silicone-containing defoamers that combine sustainability with high performance.
This article explores how BYK’s solutions—BYK-1810, BYK-1811, BYK-1815, BYK-1816, and BYK-1818 offer exceptional results in solvent-borne and solvent-free systems, ensuring optimal performance without fluorine-based components. These additives perform on par with traditional PFAS-containing products but are completely fluorine-free, aligning with environmental standards.
Addressing the PFAS Challenge
PFAS are widely used in paints, coatings, and other formulations for their efficiency in fast and spontaneous defoaming. However, their persistence in the environment and potential health implications have prompted strict regulatory controls. Manufacturers now face the dual challenge of finding alternatives that:
- Deliver comparable defoaming performance without PFAS, and
- Meet sustainability standards demanded by regulatory bodies and consumers.
BYK’s new generation of PFAS-free defoamers addresses this challenge head-on.
