Product Description Product DescriptionCOPOTHIN? is an acrylic based, low molecular weight, polymer-type thinner used in most water-based drilling fluids up to 400°F It is effective thinner/deflocculant with exceptional tolerance to high temperature, divalent cautions, pH fluctuations and salinity. It will replace traditional thinners in most applications, exceeding those products in performance and cost effectiveness. COPOTHIN? is used to maintain rheological stability in the presence of electrolyte contamination from salt, gypsum and cement. It will also aid in the prevention of high-temperature mud gelation.Applications/FunctionsDeflocculates most water-based systemsHelps minimize thermal flocculationReduces shear strength developmentAdvantagesStable at temperature up to 400°FReadily soluble in water and can be added directly to agitated mud pits Excellent performance at low concentrations Effective in the presence of salt and divalent ionsNot pH dependentEnvironmentally acceptableTypical PropertiesAppearance: Colorless to yellow, viscous liquidSpecific gravity: 1.10-1.25; pH: 4-8Boiling Point: 180-212°F; Solid Content: 45%Recommended TreatmentA typical range is 1- 4 ppb, but specific drilling conditions will dictate a suitable concentrationPackage55 GAL DRUM or 5 GAL PAIL SHARKProduct DescriptionApplications/FunctionsEZTHIN?Sulfonated TanninThinner for WBM.
