- Diacel® LTR-100 Liquid Cement Retarder Additive

Diacel^® LTR-100 Liquid Cement Retarder Additive

Diacel^®LTR-100 Powder Cement Retarder Additive is a low-temperature retarder that is typically dry blended with the cement prior to preparation of the cement slurry. Diacel® LTR-100 Powder Cement Retarder Additive is used to extend the fluid life of the cement slurry. Extending the fluid life of the cement slurry allows for the mixing and placement of cement slurries in the wellbore annulus. Diacel® LTR-100 Powder Cement Retarder Additive has a mild dispersing effect on the slurry, resulting in improved rheological properties for most cement slurries. Diacel® LTR-100 Powder Cement Retarder Additive is synergistic with Diacel^® RPM Powder and Liquid Cement Dispersant Additives, resulting in improved retardational and dispersive properties.

Diacel® LTR-100 Liquid Cement Retarder Additive is a low-temperature liquid retarder that is typically added to the mixing water prior to preparation of the cement slurry. Diacel® LTR-100 Liquid Cement Retarder Additive extends the thickening time of the cement slurry for the purpose of providing sufficient time for placement. Diacel® LTR-100 Liquid Cement Retarder Additive has a mild dispersing effect on the cement slurry, resulting in an improvement in the cement slurry rheology with most slurries.
