BYK-044 is a silicone-containing defoamer additive that provides excellent defoaming properties for aqueous systems. BYK-044 efficiently controls foam during production processes. It maintains its defoaming effect even after application. BYK-044 is suitable for use in pigment concentrates and can demonstrate considerable defoaming already during their production. This ensures a smooth production process without interruptions from foam. BYK-044 also effectively controls foam in overcoatings, allowing for efficient manufacturing of high quality end products with a uniform appearance.
