Xanthum Gum
RXSOL-81-8135-025It is high-molecular weight biopolymer, provides versatile rheology control in a wide range of brines, drilling and fracturing fluids
Product Overview
Technical Specifications
Xanthum Gum is a natural biopolymer based on poly saccharides. The average molarity is approximately 2x106 g/mol. IT is soluble in cold and hot water and yields highly viscous, shear and thinnable solutions. It is insoluble in most organic solvents. Xanthum Gum is fully soluble in water and mixtures of organic liquids with at least 60% water content. Ethanol content of up to 50% is also possible.
Xanthum Gum is stable in anionic and non Ionic systems. In cationic systems, it is not always compatible.
The solutions are pH- and temperature stable. There is almost no change in viscosity from pH 2-12.The temperature has relatively less influence on the on the viscosity of a solution of Xanthum Gum.
Xanthum Gum prevents settling of pigments and fillers and separation of the liquid phase during storage. Application is made easier through pronounced structural viscosity .The viscosity sinks when the shear force is increased. It rapidly returns to the starting value when the shear force is increased. It rapidly returns to the starting value when the sheer force is removed. The product is compatible with most commonly used binders and thickeners used in the coating industry.
Application & Dosage
Application Instructions
Advantage :
- Minimized pumping friction in lime, freshwater and saltwater muds.
- Maximized drill bit penetration.

Available Packaging & Quantities
Dosage
Depending on the requirement 0.1-0.5% calculated based on the water content.
Solutions should not contain more than 1% Xanthum Gum.Considerably higher concentrations ensure no homogenous Dispersion.
Processing
Due to its specialized chemical surface treatment, the products tend not to clump. It can be incorporated with low shear forces. Solution can be created by simply stirring it into water.
IT should be prepared an neutral to acidic pH-value- ranges. The viscosity increases in this case as a function of time until complete swelling occurs. Immediate viscosity build up can be achieved by alkalizing the solution.
Handling, Storage & Safety
Thickening and thixotropic agent for aqueous systems. Application
Xanthum Gum is suitable for use as a thickener and stabilizing additive for all aqueous coating systems and technical applications such as water thinkable lacquers, dispersion paints and plasters, glues printing inks, silicon paints as well as pigments and filler preparations.

Useful Applications
It is high-molecular weight biopolymer, provides versatile rheology control in a wide range of brines, drilling and fracturing fluids. Xanthan gum is considered non-hazardous and suitable for use in environmentally sensitive locations and applications. It is a highly dispersible powder that can be used for a variety of oilfield applications that use standard grade xanthan gum. It is readily disperses and can be mixed into water under low shear conditions without the formation of lumps and “fisheyes” often seen with non-dispersible polymers, improving utility and efficiency.
In addition to its improved dispersibility,it has the typical properties of xanthan gum for oilfield use – excellent rheological control for water-based drilling, completion and work-over fluids in a wide range of brines.
