Retarders-OBC-R30S/L

Short Description:

Summary OBC-R30S/L is a polymer based high temperature retarder. OBC-R30S/L can effectively extend the thickening time of cement paste with regularity and has no effect on other properties of cement paste. OBC-R30S/L has a rapid development of cementitious strength and is not super retarded for the top of the sealed section. OBC-R30S/L is suitable for fresh water, salt water and sea water slurry preparation. Usage range Temperature: 93-210°C (BHCT). Suggestion dosage: Solid: 0.1%-1.5% (BWO...
