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.
