Physical properties
 

Item	DS-192L	DS-192P
Appearance	Yellow semitransparent liquid	Yellow semitransparent liquid
Content(%)	33%	35%
Solvent	water	water
Remarks	Unneutralized	Neutralized

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)

Water:                           add to 100%

Item	Toynol^® DS-192L	Toynol^® DS-192P
Dispersant dosage(SOP)	1%	1%
Wetting of original powder	Quick	Quick
Shelf stability	★	★
Millbase viscosity	★	★
Dispersion fineness(μm)	≤2.5	≤2.5
Change of storage viscosity	Without thickening and thixotropy	Without thickening and thixotropy

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:          20
