Product Description Product DescriptionSHARKCMC? L filtration control additive is a technical-grade low-viscosity sodium carboxymethyl cellulose used to reduce filtration in fresh water and seawater mud systems up to 250°F. It is less effective in brines and saltwater and is not generally recommended to be used if the salinity exceed 50,000 ppm. SHARKCMC? L is used in high-viscosity, high solids or heavily weighted fluids and produces only slight increases in viscosity. Subject to bacterial degradation, a biocide should be used to prevent fermentation. SHARKCMC? L treated systems should be pretreated with either sodium bicarbonate or possibly citric acid prior to drilling cement.Applications/Functions Control filtration rates with minimal viscosity increase in freshwater and seawater mud systemsDeflocculate some seawater muds when used in low concentrationsAdvantages Temperatures stable up to 250°FWidely available and an economic source of polymer fluid-loss controlConcentrated chemical, very effective at small treatment levels Typical Properties Appearance: Off-white powderSpecific gravity: 1.59pH (5% aqueous solution): 9-11Recommended Treatment Freshwater: 0.5-1.5 ppbSeawater: 2-3 ppb Add slowly through a mixing hopper at a rate of 10-20 min/sackPackage 25 KG SACKSHARKProduct DescriptionApplications/FunctionsSHARKPAC?
