I. Performance of Potassium

Appearance: cream free-flowing powder. No lumps
Solubility at 20oC: very soluble in fresh and salt water

II. Applicable Fields

Xanthan Gum may be added to all fresh-water, salt water and gyp drilling fluids, the product has a high resistance to bi-valent salt solutions and is compatible with virtually all common drilling fluids additives.
Xanthan Gum increases the viscosity of the drilling fluid at low shear rates, thus increasing the carrying capacity for dill soilds and ensuring good hole cleaning. At high shear rates, which occur at the bit, the drilling fluid treated with XC-polymer is low-viscous, thus alos ensuring high penetration rates.
