Product Description
DOC-R32S is a polymer based high-temperature retarder.
DOC-R32S can effectively prolong the thickening time of cement slurry with strong regularity, and has no effect on other properties of cement slurry.
DOC-R32S has a rapid development in the strength of cement stone and does not cause super-retarding at the top of the sealing section. It can be used for long sealing section operations.
DOC-R32S is suitable for mixing fresh water, saltwater, and seawater.
