BYK-1610 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.
Baking Paints: Used in baking paint applications to eliminate boiling defects and control foam, ensuring a high-quality, smooth finish after curing.
Industrial Coatings: Ideal for a range of industrial coatings, enhancing their surface integrity, performance, and aesthetic appeal for consistent, reliable results across diverse applications.

Q1: What types of coating and ink systems is BYK-1610 Defoamer most effective in?
A: BYK-1610 is particularly effective in waterborne architectural coatings, industrial maintenance paints, and flexographic and gravure inks where rapid foam suppression and long-term defoaming stability are required. It performs well in both low- and medium-solids formulations with good compatibility in acrylic, styrene-acrylic, and PUD-based systems.
Q2: How should BYK-1610 be incorporated into a formulation for optimal performance?
A: For best results, add BYK-1610 during the let-down or post-addition stage, after high-shear dispersion of pigments and fillers. It can also be added during grinding if foam generation is severe at that stage—however, pre-dilution with water or a compatible solvent is recommended to ensure uniform distribution and avoid localized over-concentration.
Q3: Does BYK-1610 affect gloss, transparency, or substrate wetting in clear coats or transparent inks?
A: When used within the recommended dosage range, BYK-1610 typically has minimal impact on gloss retention or clarity in clear systems. It is formulated to provide efficient defoaming without significantly compromising surface appearance or intercoat adhesion, though final evaluation under actual application conditions is always advised.
Q4: Is BYK-1610 suitable for use in low-VOC or zero-VOC formulations?
A: Yes—BYK-1610 is a water-based, solvent-free defoamer designed to support low-VOC regulatory compliance. It contains no APEOs, no NMP, and no regulated volatile organic compounds, making it appropriate for environmentally driven formulations across architectural, industrial, and packaging applications.
Q5: What is the typical dosage range for BYK-1610 in standard coatings?
A: Dosage depends on formulation complexity, raw material interactions, and processing conditions—but BYK-1610 is generally used at low concentrations, typically ranging from 0.1% to 2.0% by weight of total formulation. Optimization through lab-scale trials is strongly recommended to balance defoaming efficiency with compatibility and film properties.
