BYK-1711 is an innovative polymer-based defoamer that is free of aromatics and silicones. It is specifically designed for radiation-curing systems, including wood coatings, industrial paints, printing inks, and adhesives. It delivers excellent foam suppression with spontaneous defoaming action, ensuring high transparency of end products and reducing the tendency for pinholes. This product enhances both the performance and aesthetic quality of formulations, making it an ideal choice for manufacturers seeking effective foam control in their applications.
Aromatic- and Silicone-Free: Formulated without aromatics or silicones, avoiding potential issues such as surface contamination, compatibility problems, or defects linked to these components.
Superior Foam Control: Provides excellent foam suppression along with spontaneous defoaming action, effectively addressing foam-related challenges during processing and application.
Enhances Transparency: Ensures high transparency of end products, making it suitable for applications where clarity is a critical requirement.
Reduces Pinholes: Minimizes the tendency for pinhole formation, improving surface smoothness and overall quality of formulations.
Coil Coatings: Improves flowability and pigment dispersion in coil coatings, contributing to even, flawless finishes on metal coils.
Industrial Paints: Applied in radiation-curing industrial paints to suppress foam, reduce pinholes, and enhance the performance and appearance of painted industrial products.
Printing Inks: Utilized in radiation-curing printing inks to manage foam, ensuring clear, precise prints with improved aesthetic appeal.

Q1: What types of coating systems is BYK-1711 Defoamer best suited for?
A: BYK-1711 is especially effective in waterborne architectural and industrial coatings, including acrylic, styrene-acrylic, and vinyl acetate-based systems. It provides reliable foam control during both production and application without compromising gloss or substrate wetting.
Q2: How does BYK-1711 compare to silicone-based defoamers in terms of compatibility and surface appearance?
A: Unlike many silicone-based defoamers, BYK-1711 is a non-silicone, mineral oil–based formulation designed to minimize the risk of surface defects such as craters, pinholes, or dewetting—especially in sensitive high-gloss or clearcoat systems.
Q3: Can BYK-1711 be added at any stage of the manufacturing process?
A: Yes—it is typically dosed during the let-down or post-addition stage for optimal dispersion and performance, but it can also be incorporated earlier in the grind phase when stable dispersion is ensured. Its low viscosity facilitates easy handling and incorporation.
Q4: Is BYK-1711 suitable for low-VOC or zero-VOC formulations?
A: Yes—BYK-1711 contains no VOCs and is compatible with modern low-VOC and zero-VOC waterborne systems. It supports compliance with environmental regulations without requiring reformulation adjustments.
