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   evaluationUse   Brookfield rotational viscometer

¬  Fineness   measureScraper   fineness meter;

¬  Viscosity   stabilityStore   millbase in 100ml wild-mouth bottle at 40   for 24 hours, measure viscosity change,    ±50% change is regarded qualified;

Recommended Applications

ü   Water-based   inks

ü     Architectural coating

ü     Wood and   furniture coatings

ü     Automotive   coatings

ü     Can coatings

ü   Anticorrosive paint

ü   Leather coatings

Operation proposals       

1.      Suggested dosage of organic pigmentBased on pigment, Toynol®   dispersants 

calculate solid content SOP)10-50%

2.      Suggested dosage of inorganic   pigment(titanium dioxide)Based on pigment, 

Toynol® dispersants   calculate solid content SOP)3-7%

3.      Do not add wetting agents separately

4.      Toynol® wetting agents can accelerate original powder   wetting

5.      Adding   Toynol®defoamers can quickly eliminate grinding foam

6.      To obtain optimal performance, Toynol®  additives must be added in water before 

resin and pigment

7.      Advise gradient test to get optimal dosage
