Product Name: Organic Bentonite (Rheological Additives) Model NO.: BK-922 Shape: Powder Usage: Sealants, Greases, Paints Color: White Packaging: 25kg Per Woven Bag Certification: ISO 9001:2008, SGS Trademark: Jingyi Transport Package: 25kg/Bag Specification: 25KG/BAG Origin: Huzhou, Zhejiang Product Description BK-922 is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systemsof low to medium polarity.1.Advantages:High gelling efficiency over low to medium polarity organic liquids.Easy of incorporation. No need for polar activator or making pregel.Consistent in rheology and thixotropy development.Easy of dispersion with excellent fineness.Good anti-sagging property and anti-sediment property.Can be added at any step,even can be used in post-addition to correct the final viscosity of a certain batch.2.Typical Properties:ColorAppearanceDensityMoisture(@105ºC,2hrs)Fineness through 200 meshLoss on Ignition( @1000ºC )WhiteFree Flowing Powder1.6g/cm3≤3.5%≥99%≤38%3.Typical Applications:Acrylic paintSilica paintAlkyd paintInks(mineral oil)Anti-corrosion paintInks(Nitro)Chlorinated rubber paintAdhesiveNitro lacquerVarnishPrimer paintLubricating greasePolyester paint4.Incorporations:BK-922belongs to the unconventional type of organoclays group, being an easy-to-disperse,self-activated organoclay, BK-922 does not require a chemical (polar) activator to reach theproper level of delamination of the organoclay platelet stacks.BK-922 can be added at any point in the manufacturing process. If addition is made withpolar activator or after grinding,better performance can be expected.5.Recommended Levels:The amount of BK-922rheology modifier required depends upon the type of organic systemand the degree of thickening or other properties desired. Addition levels are typically between0.2%-1.5% based on the total formulation weight. For high thixotropy systems or thick filmpaints, the recommended levels are between 1%-2.7%.6.
