3000rmp/min 60minPerformance evaluationCentrifugal 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 meteriscosity 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 ApplicationsWater-based inksArchitectural coatingWood and furniture coatingsAutomotive coatingsCan coatingsAnticorrosive paintLeather coatings Operation proposals Suggested dosage of organic pigment(based on pigment, Toynol® dispersants calculate solid content SOP):10-50%.Suggested dosage of inorganic pigment(titanium dioxide)(Based on pigment, Toynol® dispersants calculate solid content SOP):3-7%;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 to get optimal dosage.Packaging/storage
