USZ is modified polymer which made up of methanal and acetone.
The normal dosage is: 0.3% ∼ 0.8% USZ (BWOC), and it is not confined to this
range in some particular case.
Dissolve easily.
Increasing additive dosage, it can adjust the rheology of the cement slurry
effectively, and
reduce the consistency.
With good high temperature resistance, it can be used within 30℃ ∼ 180℃
(BHCT).
Consolidate cement stones, enhance its compression strength and control fluid
loss.
With certain retarding property.
Mixed with or without water.
Good compatibility with other additives.
