DESCRIPTION - FRITZ SC-8 is a cement dispersant that reduces the apparent viscosity and improves the rheological properties of cement a slurry.
ADVANTAGES
• SC-8 lowers the viscosity of a slurry and reduces the frictional pressure during pumping.
• The thinning of the cement slurry aids in achieving turbulent flow and mud removal in the annulus of a well.
• A lower viscosity cementing system can be mixed at a higher density by reducing the mixing water while remaining pumpable.
APPLICATION
• SC-8 is primarily a dispersant but by reducing the mixing water it improves fluid loss control.
• SC-8 is compatible with polyvinyl alcohol and salt cement slurries.
• It may be used for dispersing any API class of cement (A, C, G or H).
• It may be used with other cement additives such as fluid loss additives, silica flour, retarders, defoamers and weighting materials.
