EFKA® FA 4671 helps to prevent interfacial tension between hydrophilic pigments/extenders and binder. Advantages resulting from its wide compatibility and the combination with a polysiloxane are:

• reduced dispersing time
• stabilization of the pigment dispersion
• prevention of flooding and floating
• reduced pigment sedimentation
• reduced tendency to “orange peel”
• improved gloss and leveling

Applications

EFKA® FA 4671 is suitable for low- or high-polarity solvent systems as well as water-based coatings.

It is used to reduce flooding and settling in non-polar systems, e.g., airdrying alkyd paints. It is an effective anti-settling agent in wash and shop primers.

It improves the color acceptance of tinting bases in white latex paints, resulting in higher pigment efficiency.
