Description
l DOC-R30L is a polymer based high-temperature retarder.
l DOC-R30L can effectively prolong the thickening time of cement slurry, with strong regularity and no effect on other properties of cement slurry.
l DOC-R30L has a fast development in the strength of cement stone and does not exceed the retarding effect on the top of the sealing section, making it suitable for long sealing section operations.
l DOC-R30L is suitable for slurry preparation in freshwater, saltwater, and seawater.
