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.
