3000rmp/min 60minPerformance 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.

Remarks:Put Alumina and Toynol DS-192 series dispersing agents together through grinding, pulping, dusting and drying to get modified alumina powder. The modified powder can provide "instant" dispersion effect while soluble in water.Example2(★:Excellent ☆:Good )Experimental pigment: Carbon black C-168 , powder content 20%Organic pigment content: 20Dispersant dosage(as supplied): 30Defoamer(Toynol®): 0.1-0.3Wetting agent(Toynol®): 0-0.3(as appropriate)Water: add to 100%

After powder completely wetting, put into grinding glass beads to start timing grind.)Recommended Applications
Water-based inks
Architectural coating
Wood and furniture coatings
Automotive coatings
Can coatings
Anticorrosive paint
Leather coatings
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
StorageAs liquid material, this product should be sealed and placed in a dry, cool, well-ventilated place at room temperature
