Rhodoline DF681F is a mineral oil-based defoamer from Solvay (Rhodia, France), formulated for aqueous systems. It is a white liquid that is easy to handle and mix, making it a practical additive for a wide range of industrial applications.
Defoaming Performance:
Rapidly breaks down both large and fine bubbles while providing long-lasting inhibition of re-foaming, ensuring consistent foam control.
Maintains effectiveness across extreme conditions, including wide temperature and pressure ranges, as well as in acidic or alkaline environments, ensuring reliability in diverse settings.
Safety & Composition:
Silicone-free, reducing the risk of surface defects like craters—particularly valuable in coating applications where a smooth finish is critical.
Low toxicity, with approval for food-contact applications (e.g., vegetable washing) following safety evaluations, ensuring safety in sensitive uses.
Compatibility: Suitable for low-viscosity aqueous systems, including coatings, inks, adhesives, and detergents, integrating seamlessly without compromising product performance.
Coatings & Inks: Controls foam in latex paints (interior/exterior walls), industrial coatings, and ink production, enhancing surface quality and stability by preventing defects like pinholes.
Leather Processing: Eliminates foam in leather finishing processes, improving surface smoothness and boosting coating adhesion for better product quality.
Adhesives: Reduces bubbles in adhesive formulations, ensuring consistent bonding performance and enhancing the reliability of the final product.
