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

Dispersant dosage(as supplied):    30

Defoamer(Toynol®):               0.1-0.3

Wetting agent(Toynol®):            0-0.3(as appropriate)

Water:                           add to 100%

Millbase viscosity ★ ★ ☆
Dispersion fineness(μm) ≤2.5 ≤2.5 ≤2.5
Change of storage viscosity Without thickening and thixotropy Without thickening and thixotropy Without thickening and thixotropy


(When actual operation:First add dispersant into water, then add powder, 4000rmp/min 10min. After powder completely wetting, put into grinding glass beads to start timing grind.)
