Product Description
l DOC-R30S is a polymer based high-temperature retarder.
l DOC-R30S can effectively prolong the thickening time of cement slurry, with strong regularity and no effect on other properties of cement slurry.
l DOC-R30S has a fast development in the strength of cement stone and does not exceed the retarding effect on the top of the sealing section, it can be used for long sealing section operations.
l DOC-R30S is suitable for slurry preparation in freshwater, saltwater, and seawater.
