Notes

See HPM-20 for microfine version of this.

A selectively mined and processed, high quality sodium bentonite.
It is used for suspending, emulsifying, and as a binding agent for industrial products where a dry 200 mesh particle size is required. It contains small portions of feldspar, calcite and quartz.
Moisture is 12% as shipped.
Dry PSD: Minimum 65% finer that 200 mesh (74 microns)
Wet PSD: Minimum 94% finer that 200 mesh (74 microns)
Minimum 92% finer than 325 mesh (44 microns)
pH: 2% solids: 8.5-10.5

Viscosity: 8-30 cps @ 6.25% solids

Clays that are not kaolins, ball clays or bentonites. For example, stoneware clays are mixtures of all of the above plus quartz, feldspar, mica and other minerals. There are also many clays that have high plasticity like bentonite but are much different mineralogically.
