EFKA® FA 4642 is an additive for pigment dispersion. It reduces the interfacial tension between pigments or extenders and the vehicle.
This means:

• reduced viscosity
• stabilization of the pigment dispersion
• reduced pigment sedimentation
• increased gloss and improved flow

Applications

EFKA® FA 4642 is compatible with all solvent-free or solvent-based coating systems and does not affect the pot life of two-component systems.

EFKA® FA 4642 offers these advantages when used to disperse organically treated bentonites

• shorter dispersion time
• easier handling of bentonites gel
• improved storage stability
