Product Description DS-172 Dispersing Agent Product IntroductionChemical Compostion Solution of high molecular polymers with pigment anchoring group ApplicationsMatting agent Inorganic pigment Inorganic powder Characteristics1. High performance dispersing agents in water-based system 2. Low dosage pigment dispersion with wetting property3. Good wetting dispersing effect to pigment and fillings4. Outstanding deflocculation5. Provide powerful charge repulsion property6. Especially suitable for matting powder7. Reduce viscosity of grinding system, improve color development of millbase8. APEO free Typical Properties Item DS-171 Appearance Yellow transparent liquid Content(%) 45% Solvent Water/PropanediolGrinding operationDispersing sand mill, Glass bead(0.8-1.2mm), Filling rate 70%, 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 meterViscosity stability:Store millbase in 100ml wild-mouth bottle at 40oC for 24 hours, measure viscosity change, ±50% change is regarded qualified.Example1(★:Excellent ☆:Good )Experimental pigment: GRACE matting agent MSK-C7, powder content 20%Matting agent content: 20Dispersant dosage(as supplied): 13.3Defoamer(Toynol?): 0.1-0.3Wetting agent(Toynol?): 0-0.3(as appropriate)Water: add to 100ItemToynol?

After powder completely wetting, put into grinding glass beads to start timing grind.)Operation proposals1. Suggested dosage when dispersing matting agent(Based on matting agent, Toynol? dispersants calculate solid content SOP):20-25%.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 to get optimal dosage.
