Thickening agents guar gum

For products intended to remain stable dispersions for an extended period, a particle size of 2 p.m or less is desirable. A thickening agent is usuaUy added after the reaction has been completed and the mixture is cooled in order to prevent settling and agglomeration. Examples of thickeners are guar gum, xanthan gum, and hydroxyethylceUulose. The final products are generaUy between 40 and 50% soUds, with a viscosity of 1500 5000 mPa-s(=cP). 

AN with sufficient water to give such viscosity that the particulate material remains in suspension and hence in uniform distribution thruout the slurry. The viscosity may be improved by adding thickeners such as guar gum, polyacrylamides, etc, with or without cross-linking agents. Up to 50% NC may be replaced with TNT, Tetryl, PETN, RDX or HMX up to 25% AN may be replaced with alkali metal nitrates, such as NaNOg)...
