Wetting and dispersing additive to prevent flooding and floating of pigments
High molecular weight unsaturated carboxylic acid, combined with a very compatible organically modified polysiloxane in alkylbenzene/diisobutylketone
EFKA-5065 helps to prevent interfacial tension between the hydrophilic pigments/extenders and the binder. Advantages resulting from its poly-functional composition and the incorporation of a very compatible polysiloxane are:
reduced dispersion time
stabilization of the pigment dispersion
reduced pigment sedimentation
no formation of Bénard cells
reduced tendency to 'orange-peel'
prevention of flooding and floating
improved gloss and slip
EFKA-5065 is especially suitable for medium to high-polarity binder systems, for example:
alkyd/amino resin combinations
nitrocellulose systems
polyurethane and chlorinated polymer systems
acrylic polyisocyanate systems (2-pack acrylics)
chlorinated polymers
EFKA-5065 is not compatible with white spirit or paints which are diluted with white spirit.
High molecular weight unsaturated carboxylic acid combined with a very compatible organically modified polysiloxane in alkylbenzene/diisobutylketone. Used as a wetting and dispersing additive to prevent flooding and floating of pigments for medium to high-polarity binder systems such as alkyd/amino resin combination, nitrocellulose systems, polyurethane and chlorinated polymer systems, acrylic polyisocyanate systems (2-pack acrylics) and chlorinated polymers. Helps to prevent interfacial tension between hydrophilic pigments/extenders and binder. Offers reduced dispersion time, stabilization of pigment dispersion, reduced pigment sedimentation, no formation of Bénard cells, reduced tendency to "orange-peel" and improved gloss and slip. Gives no compatibility with white spirit.
