GENERAL DESCRIPTION
Riteks RCD-4 – White Dispersant provides superior dispersing power compared to conventional dispersants up to minimum 250F(120C). Riteks RCD-4 – White Dispersant is a high-range water-reducing admixture powder utilizing superior polycarboxylate chemistry to achieve low and stable rheology at significantly lower dosage rates than with standard dispersants. This chemistry also offers a very high salt tolerance up to 18% NaCl and widens the field of potential applications significantly. Riteks RCD-4 – White Dispersant can show retarding properties, although is often used in CaCl2 accelerated cement slurries and aids in reducing shrinkage during accelerated cement set.

APPLICATIONS & BENEFITS
APPLICATIONS
APPLICATIONS & BENEFITSUsed at the recommended levels of 0.1 to 1% by weight of cement, AFS Dispersant RS-5 can be used in:
- Primary and remedial cementing operations
- High-density and/or low fluid loss slurries
- Salt and salt-saturated slurries
- Typical temperature ranges of 40°F to 400°F (4°C to 204°C) BHCT
FEATURES & ADVANTAGES
APPLICATIONS & BENEFITS- Provides turbulent flow properties, improving mud cleanup, and cement bonding
- Facilitates mixing of high-density, reduced-water slurries
- Reduces mixing and final slurry viscosity
- Provides less retardation than conventional dispersants, resulting in earlier strength development
- Inhibits viscosifying effects caused by some fluid loss and gas control additives
- Improves annular displacement, reducing cement contamination
- Improves the performance of gas control and fluid loss additives
- Improves bonding to the formation and pipe
- Compatible with virtually all API, ASTM, and pozzolan cements, and most Riteks cement additives
