Performance evaluation
Example1(★:Excellent ☆:Good )
Experimental pigment: phthalocyanine green G, powder content 30%
Pigment content: 30
Dispersant dosage(as supplied): 20
Defoamer(Toynol®): 0.1-0.3
Wetting agent(Toynol®): 0-0.3(as appropriate)
Water: add to 100%
Example2(★:Excellent ☆:Good )
Experimental pigment: permanent yellow P.Y.12, powder content 35%

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.

Recommended Applications
- Water-based inks
- Architectural coating
- Wood and furniture coatings
- Automotive coatings
- Can coatings
- Anticorrosive paint
- Leather coatings
- Suggested dosage of organic pigment(Based on pigment, Toynol® dispersants calculate solid content SOP):10-50%;
- Do not add wetting agents separately;
- Toynol® wetting agents can accelerate original powder wetting;
- Adding Toynol® defoamers can quickly eliminate grinding foam;
- To obtain optimal performance, Toynol® additives must be added in water before resin and pigment;
- Advise gradient test;
