Product Name: Modified Bentonite for Solvent -Organophilic Clay Model NO.: BK-127 Shape: Powder Usage: Paint, Inks, Nitro Lacquer Color: Light Yellow Packaging: 25kg Per Woven Bag Certification: ISO 9001:2008 Quality: Industrial Colour: Light Yellow Transport Package: 25kg/Bag Specification: 25KG/BAG Origin: Huzhou, Zhejiang Product Description BK-127is an organoclay for solvent-basedsystems of high polarity.1. Advantages:☆High gelling efficiency over highpolarity organic liquids, especiallyinaromatic,alcohol, ketone,and the compoundsof 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 Applications:AcrylicpaintPrimer paintAlkydpaint Silica paintAnti-corrosion paintSolvent epoxy paintBituminous paintInks(mineral oil)Container paintInks(Nitro)Industrial paintNitro lacquerMarine paint4. Incorporations:BK-127belongs to the conventional type of organoclay group, which requiresmechanical energy, shear forces applied with a goods dispersion equipment, and a chemical (polar) activator to reach the proper level of delamination of the organoclayplatelet stacks.Polar Activator:Dosage of polar activator (such as 95%ethanol, 95%methanol,95%acetoneorpropylene carbonate) is 30%-50% byweightof 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-127rheology modifierrequired depends upon the typeof 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
