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 definitionsHigh 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%

Performance tests – Test methods
Test MethodViscosity / 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 meter
