EFKA 2720 Defoamer

EFKA PB2720 (EFKA-2720), a silicone-free defoamer, is designed for solvent-based coating systems, ideal for unsaturated polyester, epoxy resins, and PVC compounds. It offers strong defoaming and long-term anti-foaming capabilities, effectively removing both microfoam and macrofoam—particularly suited for high-shear or high-speed applications. It meets environmental standards, ensuring safety and reliability.

Features Of EFKA 2720 Defoamer

  1. Efficient Defoaming: Rapidly eliminates microfoam and macrofoam, enhancing surface quality.

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

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

  4. Eco-Friendly: Complies with environmental standards, suitable for indirect food contact applications.

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

Typical Applications Of EFKA 2720 Defoamer

  1. Unsaturated Polyester: Applied in SMC/BMC gel coats and synthetic mortars to create a smooth surface.

  2. Epoxy Resins: Used in two-component epoxy resin coatings to boost coating effects.

  3. PVC Compounds: Added to PVC composites to resolve bubble issues.

  4. Pigmented or Non-Pigmented Resin Systems: When paired with EFKA FA 4644, it lowers viscosity and improves air release performance.
