Effect of Solids Concentration on Viscosity
Solution Preparation
GlucoSol 621 is readily soluble in water with rapid hydration. Sufficient agitation is necessary to avoid excessive lumping of the polymer as it is added to the solution. The time and amount of agitation required for complete hydration of the polymer will vary with solids concentration and water make-up temperature.
Effects of Shear on Viscosity
Effect of Temperature on Viscosity
Solution Preservation
The chemical substitution of GlucoSol 621 provides enhanced solution biostability. Extended storage could result in viscosity reduction due to microbial or enzymatic attack. Stored solutions should be protected by the use of a preservative. GlucoSol 621 is also available with a preservative treatment.
Hydration Profile
Thixotropy
Solutions of GlucoSol 621 exhibit near pseudoplastic behavior. Viscosity decreases with increasing shear and when the shear is removed the original viscosity is immediately recovered. Thixotropic solutions regain their original viscosity with a time element.
Packaging & Availability
- Packaging Type
- Availability
GlucoSol 621 is available in 50 lb. multi-wall poly-lined paperbags or 2000 lb supersacks for truckload and LTL shipments.
Storage & Handling
- Storage And Handling
GlucoSol 621 exhibits excellent storage stability if kept dry in its original package. Shelf life can be affected by storage conditions such as temperature, humidity, and overall surroundings of the storage area.
