Substantially enhance the compaction, strength, and impermeability of the set cement.
Suitable for use in both fresh and saltwater, with a salt tolerance of up to 5% brine.
Operable in temperatures below 150°C (302°F, BHCT).
Contributes to reducing the fluid loss in the cement slurry.
No water preparation is required, as the product is ready for use.
When using CT610L for testing, it is essential to add defoamer to prevent the formation of bubbles.
The recommended dosage range for CT610L is 3.0-20.0% by weight of cement.
CT610L High-Performance Latex Cement Additive
Enhance Impermeability and Structural Integrity in Challenging Wellbores
CT610L is a specialized liquid latex additive designed to transform the physical properties of set cement. By significantly increasing compaction and reducing permeability, CT610L creates a durable, high-strength barrier that is essential for preventing gas migration and ensuring long-term zonal isolation.
Core Benefits
Superior Compaction: Drastically enhances the density and impermeability of the set cement, making it ideal for high-pressure environments.
Advanced Fluid Loss Control: Acts as a powerful agent to reduce fluid loss (≤50 ml in salt systems), maintaining slurry stability during the transition phase.
Salt & Temperature Resilience: Maintains peak performance in both fresh and saltwater (up to 5% brine) at temperatures up to 150°C (302°F BHCT).
Ready-to-Use Convenience: Requires no complex water preparation; the liquid is formulated for direct addition to the mixing system.
Gas Migration Prevention: The latex film-forming properties block micro-pores, providing an excellent defense against gas channeling.

Dosage: The recommended concentration is 3.0% – 20.0% BWOC (By Weight Of Cement), depending on the specific well requirements for fluid loss and strength.
Defoaming Requirement: Because latex can generate foam during high-speed mixing, it is essential to add a defoamer during the testing and mixing process to ensure slurry density accuracy.
Compatibility: CT610L is compatible with most common cement dispersants and retarders, but pre-job lab testing is always recommended to optimize thickening time.
