EFKA 2580 Defoamer

EFKA-2580, a modified polydimethylsiloxane defoamer, is designed for diverse water-based coatings and grinding color pastes. It excels in defoaming and long-term anti-foaming, effectively clearing both microfoam and macrofoam—especially suited for high-shear or high-speed applications. It adheres to environmental standards, ensuring safety and dependability.

Features Of EFKA 2580 Defoamer

  1. Efficient Defoaming: Swiftly eliminates microfoam and macrofoam, upgrading surface quality.

  2. Long-Lasting Anti-Foaming: Delivers continuous foam suppression, ideal for high-shear environments.

  3. High Compatibility: Works well with various water-based systems, including pure acrylic and styrene-acrylic emulsions.

  4. Eco-Friendly: Meets environmental standards, applicable for indirect food contact scenarios.

  5. Cost-Effective: Boasts a high cost-performance ratio, fit for large-scale use.

Typical Applications Of EFKA 2580 Defoamer

  1. Water-Based Acrylic Systems: Applied in water-based acrylic coatings to achieve bubble-free and pinhole-free surfaces.

  2. Low Polyvinyl Chloride Dispersion Coatings: Suitable for low polyvinyl chloride dispersion coatings, enhancing coating effects.

  3. Alkyd Resin/Polyurethane Systems: Used in alkyd resin and polyurethane coatings to boost surface smoothness.

  4. Grinding Color Pastes: Ideal for high pigment-to-binder ratio and low-viscosity pigment concentrates, resolving bubble issues during application.
