Cement Dispersant

Type 1: High Temperature Dispersant (SRC-007) up tp 380℉ for Oil Well Cement

Product Description
SRC-007 can adjust the electric charge on the surfaces of cement particles to achieve proper cement rheology, contributing to reduced pump pressure, enhanced circulating efficiency and convenient operation.

Characteristics
SRC-007 is a modified polymer which made up of methanol and acetone.
Suggested dosage: 0.3﹪~0.8﹪.
Soluble easily.
Increasing additive dosage, it can adjust the rheology of the cement slurry effectively and reduces the consistency.
With good high temperature resistance performance, with applied temperature ranging 30℃～180℃(BHCT).
Consolidates cement stones, enhances its compression strength and controls fluid loss property.
With a certain retarding properties.
Mixed with or without water.
Good compatibility with other additives.

Type 2: Super HT Anti-salt Dispersant (SRC-21L) up to 428℉ for Oil Well Cement

Product Description:
SRC-21L is a dispersant of brown liquid. It has good dispersing and friction-reducing effects in half saturated or saturated brine. It not only can improve the fluidity and the flow behavior index of cement slurry and decrease the consistency, but also significantly improve the flow patterns and fluidity of cement slurry while it has a good yield value and well stability under high temperature.

Interaction with Other Additives:
It is compatible with other additives, adapt to all kinds of water.
