HT retarder TR20L

 Description

TR20L is a kind of high temperature retarder compounded by organic synthesis unit, which has a good linear relationship between thickening time and dosage.

 TR20L has good salt resistance and compatibility with most additives.

 TR20L has strong adaptability to the quality of cement, and has no adverse effect on the strength development of cement paste.

 TR20L and TMS154L are used for high temperature gas channeling prevention cementing.

 TR20L has a strong dispersing effect when used at high temperature. It can cooperate with TAS153 or TAS314L to ensure the settlement stability of cement slurry.
