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 proposal
  1. Suggested dosage of organic pigment(Based on pigment, Toynol® dispersants calculate solid content SOP):10-50%;
  2. Do not add wetting agents separately;
  3. Toynol® wetting agents can accelerate original powder wetting;
  4. Adding Toynol® defoamers can quickly eliminate grinding foam;
  5. To obtain optimal performance, Toynol® additives must be added in water before resin and pigment;
  6. Advise gradient test;
