Solvent | Water |
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.

Operation proposals
1. Suggested dosage of high color black pigment(Based on pigment, Toynol® dispersants calculate solid content SOP):50-80%.
2. Suggested dosage of inorganic pigment(titanium dioxide)(Based on pigment, Toynol® dispersants calculate solid content SOP):3-7%.
3. Do not add wetting agents separately.
4. Toynol® wetting agents can accelerate original powder wetting.
5. Adding Toynol® defoamers can quickly eliminate grinding foam.
6. To obtain optimal performance, Toynol® additives must be added in water before resin and pigment.
7. Advise gradient test to get optimal dosage.
