Application & Advantages

Application:
Premium grade welan gum WG-P biopolyer is a high efficiency, pseudoplastic viscosifier and suspension agent used in water based drilling, workover and completion fluids. Welan gum is also used in hydraulic fracturing fluids and cementing grouts, foundary coating, pigment suspensions, cement or concrete viscosifier, tire sealant and paint thickeners.

Advantages:
High-preformance viscosity improver
High viscosity under low concentration
High viscosity under slow speed shearing rate
Pseudoplasticity thinning under high shear
Good stability in high salt and high temperature condition
Excellent water solubility
Good water holding capacity

Package

Dissolution
The dissolution of the product depends on the medium and the process: it is improved by heat-treatment (time, temperature), shear-stress (propeller, exchanger, homogenizer). A complete dissolution can be obtained in cold conditions.

Packaging & Storage
WG-P is packaged in 50lb or 55lb plastic lined 4-layer paper bags and shipped via an approved common carrier. DOT classification – Non Hazardous.

Shelf Life
WG-P has a shelf life of 24 months from date of manufacture when stored in a clean dry area.
