EFKA 4008 Modified polyurethane Efka Additives Dispersing agents >> Polymerics Coatings >> Solventborne Coatings >> Solvent-Free/ High-Solids Architectural / Decorative methoxypropylacetate, methoxypropanol Properties: EFKA-4008 is a polymeric dispersant for stabilizing inorganic and organic pigments. This results in: reduced dispersion time improved gloss prevention of flooding and floating problems higher colour strength Due to its particularly good combination of price and performance, EFKA-4008 is a very attractive substitute for conventional wetting and dispersing agents. Application: EFKA-4008 has been developed for use in universal solvent-based pigment concentrates, particularly for use in systems free of aromatic solvents. EFKA-4008 can also be used as a general dispersing agent for all aromatic-free solvent-based architectural finishes. Addition: Calculation method for the required amount of active ingredient on pigment: Inorganic pigments : 10% of oil absorption value Organic pigments : 25 - 50% of BET-value Carbon blacks : 20% of DBP absorption value Incorporation: EFKA-4008 should be incorporated in the mill base before adding the pigments.
