EFKA® PB 2021 can be used as a silicone-free defoamer for various coating systems. It functions well during the application of paints and lacquers and also prevents the entrapment of air during processing steps such as stirring, pumping etc.

In addition, EFKA® PB 2021 helps to prevent surface irregularities to give the smoothest possible surface.

EFKA® PB 2021 is especially suited for solvent-based coatings if foam formation is a problem when applied by spraying or curtain coating. It can also be used in:

• polyurethane coatings
• acid-curable coatings
• air-drying and baking alkyd paints
