Product Description Toynol? DS-195L/195H Dispersing AgentProduct IntroductionCharacteristics High performance dispersing agents in water-based system Good wetting effect to pigment and fillings Outstanding deflocculation Provide powerful charge repulsion property Suitable for various powder Reduce viscosity of grinding system, improve color development of millbase APEO free Chemical ComponentsSolution of high molecular polymers with pigment anchoring group Highly Recommended ApplicationsIron oxide, Transparent iron oxideTitanium DioxideCarbon blackOrganic pigments Typical PropertiesItemDS-195LDS-195HAppearanceYellow transparent liquidYellow transparent liquidContent(%)40%40%SolventwaterwaterGrinding 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 meteriscosity 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: transparent red iron oxide TR-718, powder content 40%Inorganic pigment content: 40Dispersant dosage(as supplied): 40Sodium hydroxide: Appropriate amount(PH mixed to 8-9)Defoamer(Toynol?): 0.1-0.3Wetting agent(Toynol?): 0-0.3(as appropriate)Water: add to 100ItemToynol?
