A highly effective foam suppressant that swiftly neutralizes foam formation in cement slurry.
It effectively inhibits and removes gas from the slurry.
It disperses well in the cement slurry, preventing the formation of foam caused by other additives.
It has a minimal impact on other characteristics of the cement slurry.
The recommended dosage range is 0.2-0.8% by weight of cement.
The ultimate dry-mixed solution for salt-saturated and high-durability cementing.
CT210S is an advanced gray powder latex designed to significantly enhance the mechanical properties of set cement. Unlike standard liquid additives, CT210S is engineered for dry-mixing, offering superior logistics and storage while providing extreme salt tolerance up to saturation. It is the preferred choice for improving compaction, reducing permeability, and increasing the "toughness" of the cement sheath to withstand tectonic stresses.
Extreme Salt Tolerance: Operates flawlessly in environments ranging from fresh water to saturated brine.
Enhanced Physical Properties: Improves cement compaction and toughness while drastically reducing permeability to prevent gas migration.
Dry-Mix Convenience: Eliminates the need for liquid handling equipment; no specific water quality is required for mixing.
Zero Free Fluid: Ensures a perfectly homogenous slurry even at high temperatures (90°C), preventing water pockets and weak spots.
High Compressive Strength: Achieves >14 MPa within 24 hours, ensuring rapid set-time and wellbore stability.

Application: Specifically designed for wells where liquid latex storage is impractical or where saturated salt systems are required.
Mixing: Dry-blend CT110S with the cement before adding to the mixing water.
Storag: Store in a cool, dry, ventilated area. Stack height should not exceed 8 bags to prevent caking.
Shelf Life: 18 months. Performance should be verified via laboratory testing if used after expiration.
