Deretrog-400
Deretrog-400 is a liquid cement additive made from finely divided, high surface-area silica. Deretrog-400 cement additive can be used as an extender for lightweight cements and a compressive-strength enhancer for low- temperature, lightweight cements. This product also imparts thixotropy to some cement slurries and acts as a low-temperature accelerator for salt slurries. Deretrog-400 cement additive can be used in wells with bottom-hole circulating temperatures (BHCTs) between 60° and 400°F (16° and 204°C).
