EFKA® FA 4654
Dispersant for low-polar to medium-polar systems and bentonite gels.
EFKA® FA 4654 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 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. EFKA® FA 4654 can cause discoloration in nitrocellulose varnishes.
