Grinding operation
Dispersing sand mill, Glass bead(0.8-1.2mm), Filling rate 70%
3000rmp/min 60min
Performance evaluation
Centrifugal stability: take 20ml millbase into centrifuge tube, centrifuge 10 min under condition of 3000r/min, then take out to observe the layering of millbase. Pour out liquid and calculate amount and percentage of precipitate.
Viscosity evaluation:Use Brookfield rotational viscometer.
Fineness measure:Scraper fineness meter
Viscosity stability:Store millbase in 100ml wild-mouth bottle at 40ºC for 24 hours, measure viscosity change, ±50% change is regarded qualified.
Example1(★:Excellent ☆:Good )
Experimental pigment: Alumina powder, powder content 60%
Pigment content: 60
Dispersant dosage(as supplied): 1.8
Defoamer(Toynol®): 0.1-0.3
Wetting agent(Toynol®): 0-0.3(as appropriate)

Operation proposals
1. Suggested dosage of Alumina powder(Based on pigment, Toynol® dispersants calculate solid content SOP):0.5-1%.
2. Suggested dosage of neutral color carbon black(Based on pigment, Toynol® dispersants calculate solid content SOP):50-100%.
3. Suggested dosage of conductive carbon black(BP-2000)(Based on pigment, Toynol® dispersants calculate solid content SOP):50-60%.
3. Toynol® wetting agents can accelerate original powder wetting.
4. Adding Toynol® defoamers can quickly eliminate grinding foam.
5. To obtain optimal performance, Toynol® additives
