This means: reduced dispersion time stabilization of the pigment dispersion decreased pigment sedimentation reduced tendency to sag during application on vertical surfaces prevention of flooding Application: EFKA-5054 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. EFKA-5054 is especially suitable for non-polar to medium-polar binder systems, ie. air-dried alkyd resins, chlorinated polymers, alkyd/amino resin combinations and epoxies. EFKA-5054 can cause discolouration in nitrocellulose varnishes. Incorporation: When used in mill-bases, add before grinding. In Bentonite dispersions use as follows: 85 - 87 parts of solvent 10 parts of Bentonite 5 - 3 parts of EFKA-5054 --------------------------------- 100 parts Hight molecular weight wetting and dispersing additive to prevent sedimentation and flooding of pigments.Helps to prevent interfacial tension between the hydrophilic pigments/extenders and the binder, forming a lattice structure with the pigments.Provides stabilization of the pigment dispersion. Decreases pigment sedimentation. Reduces tendency to sag during application on vertical surfaces. Prevention of flooding. Has a tendency to become hazy at low temperatures but this process can be reversed by heating. Is used for dispersing organophilic Bentonites. Reduces dispersion time. Improves the storage properties of the final paste. Gives a thixotropic, easily processed paste-product. Suitable for non-polar to medium-polar binder systems, ie. air-dried alkyd resins, chlorinated polymers, alkyd/amino resin combinations and epoxies. Can cause discolouration in nitrocellulose varnishes. Addition: 0.5 - 2.0% based on inorganic pigments. When used in mill-bases, add before grinding. In Bentonite dispersions, add 85 - 87 parts of solvent, 10 parts of Bentonite, 5 - 3 parts of the carboxylic acid salts.
