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
• iscosity stability:Store millbase in 100ml wild-mouth bottle at 40ºC 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

• Water-based inks
• Architectural coating
• Wood and furniture coatings
• Automotive coatings
• Can coatings
• Anticorrosive paint
• 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;

Handling
