Diacel® HTR-100 Powder Cement Retarder Additive is a mid-range cement retarder, effective between 175 to 275 °F. The powder form is typically dry blended with the cement prior to preparation of the cement slurry. Diacel® HTR-100 Liquid Cement Retarder Additive is typically added to the mixing water prior to preparation of the cement slurry.
Diacel® HTR-100 Powder or Liquid Cement Retarder Additive extends the thickening time of the cement slurry to provide sufficient time for placement. It has a mild dispersing effect on the cement slurry that reduces the concentration of dispersant required and inhibits premature slurry gelation with most cement slurries. Diacel® HTR-100 Powder or Liquid Cement Retarder Additive improves the performance of most fluid-loss agents and is particularly beneficial when used with synthetic polymer additives.
