and surfactant

Highly Recommended   Applications

Phthalocyanine organic pigments

Azo   organic pigments

Other organic   powder materials

Titanium   Dioxide

 

 

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 undercondition 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 40℃ for 

24 hours, measure viscosity change,  ±50%   change is regarded qualified;

(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.)

 

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 pigment(Based 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;

Packaging/storage
