Dispersant needs to cover whole pigment surface to provide stabilization
 Correct dosage level depends on pigment surface area
 Actual dosage needs to be determined with ladder study
Dispersing agents – Basic definitions
High Molecular Weight Dispersing Agents
Starting point (% active dispersant/pigment) recommendations
 Organic pigments: 20-50 % of BET value or surface area
 Blue, green, violet (typically higher surface areas) start at 25%
 Red, yellow, orange (typically lower surface areas) start at 35%
 Inorganic pigments: 10% of oil absorption value
 Carbon blacks: 20%-50% of DBP absorption value
 LCC carbon blacks, start at 20%
 HCC carbon blacks, start at 40%

Test Method
Viscosity / Stability Measurement of mill base viscosity at various shear rates before and after storage at
50°C
Color strength /
Rub-out / Chroma
Addition of pigment concentrate to a white (or black) base paint. Application on black
and white card and check rub-out: Measurement by colorimeter. Chroma is the
saturation of a color, the higher the chroma the “cleaner” a color
Weathering
Accelerated weathering according SAE J1960 (CAM-180) to investigate changes in
coloristic of a tinted aluminum effect coating (alu-reduction)  test running
Gloss Check influence of dispersing agents on gloss of the tinted paints using a gloss
