1. Product Overview
(1) The anti-channeling fluid loss agent is a multicomponent copolymer and has the function of controlling and reducing fluid loss.
(2) Enhance the suspension stability of the cement slurry system, while maintaining the fluidity of the slurry to prevent settlement.
(3) The thickening is stable, and the strength development is well correlated with time.
(4) The cement slurry has short transition time and anti-gas channeling performance.
(5). Applicable temperature: below 180℃ ((356℉, BHCT).
(6). It has good compatibility with other additives.
