1. Product Overview
(1). DOC-FL401-A is a kind of multi-component copolymer, which can effectively control water phase to formation filtration in cement slurry.
(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). It has a certain anti gas channeling performance.
(5). Applicable temperature: below 180 ℃ ((356℉, BHCT).
(6). It has good compatibility with other additives.
