Properties: EFKA-5055 helps to prevent interfacial tension between the hydrophilic
pigments/extenders and the binder, forming a lattice structure with the
pigments at the same time. This means:
reduced dispersion time
stabilisation of the pigment dispersion
decreased pigment sedimentation
reduced tendency to sag during application on vertical surfaces
prevention of flooding
Application: EFKA-5055 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-5055 is especially suitable for non-polar to medium-polar binder
systems, i.e. air-dried alkyd resins, chlorinated polymers, alkyd/amino
resin combinations and epoxies.
EFKA-5055 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-5055 -----------------------------------------
100 parts
Hight molecular weight electroneutral wetting and dispersing additive. Becomes hazy at low temperatures but this process can be reversed by heating. Helps to prevent interfacial tension between the hydrophilic pigments/extenders and the binder, forming a lattice structure with the pigments. Reduces dispersion time. Provides stabilization of the pigment dispersion. Decreases pigment sedimentation and flooding. Reduces tendency to sag during application on vertical surfaces.
