Product Name: High Gelling Efficiency Organophilic Clay Model NO.: BK-923 Usage: Paint, Ink, Adhesive, Varnish Color: Light Yellow Packaging: 25kg Per Woven Bag Certification: ISO 9001:2008 Transport Package: 25kg/Bag Origin: Huzhou, Zhejiang Product Description BK-923is an organoclay (tetraallkyl ammonium bentonite) for solvent-basedsystems of low, medium and high polarity.1.Advantages:☆High gelling efficiency overlow,mediumand highpolarity 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.In suitable systems, it can reach 5μor even less.☆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 through200 meshLoss on Ignition( @1000ºC)Light YellowFree Flowing Powder1.7g/cm3≤3.5%≥99%≤38%3.

Incorporations:BK-923belongs to the unconventional type of organoclays group, being an easy-to-disperse, self-activated organoclay,BK-923does not require a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.BK-923can be added at any point in the manufacturing process. If addition is made with polar activator or after grinding,better performance can be expected.5. Recommended Levels:The amount of BK-923rheology modifierrequired depends upon the type of organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%-1.5% based on the total formulation weight.6. International Countertypes: Bentone®SD-2, Claytone®HY,Claytone®APA
