Performance   evaluation

¬    Fineness measureScraper fineness meter;

¬    Shelf stability: Take a certain amount of Cerium   oxide slurry into measuring cylinder with stopper, place 5 days at 40 constant temperature and   observe layering of conductive black slurry after a period.

¬  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

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

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

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 inorganic pigmentBased on pigment, Toynol®   

dispersants calculate solid content SOP)8-15%

2.      Suggested dosage of neutral color carbon   blackBased on pigment, Toynol® dispersants   calculate solid content SOP)50-100%

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
