EFKA® PA 4450
Polymeric dispersing agent for organic and inorganic pigments in non-aqueous systems; especially designed for high-quality coatings and pigment concentrates.
EFKA® PA 4450 is a polymeric dispersant for inorganic and organic pigments in non-aqueous, polar and non-polar coatings. This clear liquid avoids flocculation of pigments, increases color strength and also reduces grinding time. It is a carboxyl functional polymer that can be used in all systems independent from its polarity, e. g. alkyds, PE, acrylics. 2 - component polyurethane paints, 2 - component epoxy paints, unsaturated polyester. The application in systems with low polarity is possible as well. EFKA® PA 4450 is used in combination with all commonly used solvents. It shows good solubility even with isoparaffins, which makes it very useful for these systems. It also shows excellent performance when used as a dispersant in pigment pastes.
