Retarder-OBC-R31S/L

Short Description:

OBC-R31S/L is a polymer based high temperature retarder.


Product Detail

Summary

OBC-R31S/L is a polymer based high temperature retarder.

OBC-R31S/L can effectively extend the thickening time of cement paste with regularity and has no effect on other properties of cement paste.

OBC-R31S/L has a rapid development of cementitious strength and is not super retarded for the top of the sealed section.

OBC-R31S/L is suitable for fresh water, salt water and sea water slurry preparation.
