Product DescriptionModel NO.: YH-908AType: High Gelling EfficiencyColor: WhiteColour: WhitePackage: 25kg kraft paper bagOrigin: Huzhou, ZhejiangClassification: Chemical AdditivesAppearance: PowderQuality: IndustrialTrademark: YuhongYH-908A is an organoclay (tetraallkyl ammonium bentonite) for solvent-based systems of low to medium polarity. 1. Advantages: High gelling efficiency over low to medium polarity organic liquids. Ideal thixotropy ,anti-sagging,anti-sediment property. Imparts particle suspension, preventing hard settling of pigment and fillers. Exerts strong film reinforce action in organic binder systems. Good dispersion performance. 2.

Incorportions: YH-908A 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%-60% by weight of YH-908A. 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 YH-908A 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®38, Claytone®40, Tixogel®VP-A
