Product Description BK-127 is an organoclay for solvent-based systems of high polarity. 1. Advantages: ☆ High gelling efficiency over high polarity organic liquids, especially in aromatic, alcohol, ketone, and the compounds of above. ☆ Produce reproducible thixotropic consistency over a wide temperature range.☆ Imparts particle suspension, preventing hard settling of pigment and fillers.☆ Exerts strong film reinforce action in organic binder systems. 2. Typical Properties: ColorAppearanceDensityMoisture(@105oC,2hrs)Fineness through 200 meshLoss on Ignition( @1000oC )Light YellowFree Flowing Powder1.7g/cm3≤3.5%≥98%≤35% 3. Typical Applications:Acrylic paintPrimer paintAlkyd paint Silica paintAnti-corrosion paintSolvent epoxy paintBituminous paintInks(mineral oil)Container paintInks(Nitro)Industrial paint Nitro lacquerMarine paint 4. Incorporations:BK-127 belongs to the conventional type of organoclay group, which requires mechanical energy, shear forces applied with a goods dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of the organoclay platelet stacks.Polar Activator: Dosage of polar activator (such as 95%ethanol, 95%methanol, 95%acetone or propylene carbonate) is 30%-50% by weight of BK-127.It is always recommended to determine the proper level of addition by experiment. Either defect or excess of chemical activator would result in poorer viscosity development.5. Recommended Levels:The amount of BK-127 rheology modifier required depends upon the type of organic system and the degree of thickening or other properties desired. Addition levels are typically between 0.2%-2.0% based on the total formulation weight.6. International Countertypes: Bentone?27, Tixogel? VZ
