SSR-21 is a semi-synthetic low-temperature retarder engineered to provide reliable and cost-effective set-time control in cementing operations ranging from 100°F (38°C) to 220°F+ (105°C). Developed by the Riteks R&D laboratory, this additive is designed to function as a single, versatile retarder across a broad low-to-mid temperature window, reducing the need for multiple products. SSR-21 delivers predictable performance, simplified slurry design, and consistent results, making it an efficient solution for a wide variety of cementing applications.
SSR-21 is ideal for primary cementing and remedial jobs in low to mid-temperature environments where extended pump time and precise control over set time are critical. Its compatibility with a broad range of cement grades and slurry systems makes it a flexible and dependable choice across land and offshore operations.
