EFKA PU 4063
EFKA PU 4063
EFKA® PU 4063 is a dispersing additive for organic and inorganic pigments in high-quality solvent-based pigment pastes. It reduces the dispersing time and the mill base viscosity and thus facilitates the formulation of highly concentrated pigment pastes. After the pigment paste has been blended into paint, EFKA PU 4063 prevents flooding and floating of pigments and promotes excellent gloss and high colour intensity.
This material is readily compatible with a wide range of binder types. Pigment pastes based on EFKA PU 4063 can therefore be used in 2- component polyurethane paints, 2 – component epoxy paints, unsaturated polyester, stoving paints and air-drying paints.
EFKA PU 4063 should be blended with the pigments in the mill base. The optimal amount to be added to a given system must be determined by testing. Usually it is in the range from 1 to 5% relative to the inorganic pigments or 15 to 50% relative to the organic pigments
