Efka® PU 4063 is a dispersing additive for organic and inorganic pigments in high-quality solvent-based pigment pastes.
Efka® PU 4063 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 color intensity.
Efka® PU 4063 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.
