It reduces the interfacial tension between pigments or extenders and the vehicle. This product is compatible with all solvent or solvent-free coating systems. The pot-life of two-pack systems is not affected. In the dispersion of organically treated Bentonites, the use of EFKA® FA 4642 shortens dispersion time, provides easier handling of the Bentonite gel, and improves storage stability. Vea Menos | |

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. Vea Menos |
