Riteks RCD-4 provides superior dispersing power compared to conventional dispersants up to minimum 250°F (120°C). RCD-4 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 offer a very high salt tolerance up to 18% NaCl & widens the field of potential applications significantly. RCD-4 can show retarding properties, although is often used in CaCl2 accelerated cement slurries and aids in reducing shrinkage during accelerated cement set.
Riteks RCD-3 is a highly effective water-soluble polymer dispersant used in normal to high density, low fluid loss slurries that can be easily pumped in turbulent flow. This dispersant was developed to improve performance characteristics in cement slurries for workability, and is highly effective in salt and salt-saturated slurries.
Riteks RCD-2 is a highly effective dispersant in cement slurries to improve the flow properties of the slurry, reduce hydraulic horsepower requirements, and allow removal of the mixing water resulting in a more dense cement slurry. With the use of Riteks RCD-2, cement slurries can be tailored for specific well requirements providing optimum slurry characteristics for any down hole condition.
