Potters Q-Cel agent consists of hollow microspheres with a special hydrophilic coating to help reduce dusting and enhance mixability. This material is intended for low- to intermediate-pressure Tuned®Light cementing applications, with microsphere properties falling between Spherelite®particles and HGS beads.
The lightweight microspheres of Potters Q-Cel agent provide a means of preparing 5- to 14-lbm/gal lightweight cement slurries, which can develop adequate compressive strength in a minimum period of time, even when the slurries experience relatively low curing temperatures.
Hollow spheres are pressure sensitive, and once the strength of each individual Potters Q-Cel™ microsphere is exceeded, the sphere will crush or crack, and the hollow spaces will fill with liquid, resulting in a gradual increase in slurry density as the pressure on the slurry is increased.
Potters Q-Cel Agent is a lightweight cement additive offering the following benefits
Compressive strength enhancement of the slurry at low- to moderate pressure
Compatibility with all currently used cementing addivies
