Dispersions, Resins and Additives
Efka® FA 4654 AN
Dispersant for low-polar to medium-polar systems and bentonite gels.
Efka FA 4654 AN helps to prevent interfacial tension between the hydrophilic pigments/extenders and binder, forming a lattice structure with the pigments at the same time. This means: reduced dispersion time, stabilization of the pigment dispersion, reduced pigment sedimentation, reduced tendency to sag during application on vertical surfaces, and prevention of flooding. It is a high molecular weight carboxylic acid salts. Efka FA 4654 AN is ideal for dispersing organophilic bentonites, because it reduces dispersion time, improves the storage properties of the final paste and gives a thixotropic, easily processed paste product. It is especially suitable for non- to medium-polar binder systems, ie. air-dried alkyd resins, chlorinated polymers, alkyd/amino resin combinations and epoxies.
