Typical Properties
Item | DS-171 |
Appearance | Yellow transparent liquid |
Content(%) | 45% |
Solvent | Water/Propanediol |
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: GRACE matting agent MSK-C7, powder content 20%
Matting agent content: 20
Dispersant dosage(as supplied): 13.3
Defoamer(Toynol®): 0.1-0.3

(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.)
Operation proposals
1. Suggested dosage when dispersing matting agent(Based on matting agent, Toynol® dispersants calculate solid content SOP):20-25%.
2. Do not add wetting agents separately.
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 must be added in water before resin and pigment.
6. Advise gradient test to get optimal dosage.
As liquid material, this product should be sealed and placed in a dry, cool, well-ventilated place at room temperature
