EFKA® FA 4654 helps to prevent interfacial tension between hydrophilic pigments/extenders and binder, forming a lattice structure with the pigments at the same time. This means:

• reduced dispersing time
• stabilization of the pigment dispersion
• reduced pigment sedimentation
• reduced tendency to sag during application on vertical surfaces
• prevention of flooding

Applications

EFKA® FA 4654 is ideal for dispersing organophilic bentonites because it reduces dispersion time, improves storage properties of the final paste and gives a thixotropic, easy-to-process paste.

EFKA® FA 4654 is especially suitable for non- to medium-polar binder systems, i.e., air-drying alkyd resins, alkyd/amino resin combinations, chlorinated polymers and epoxies.

EFKA® FA 4654 can cause discoloration in nitrocellulose varnishes.
