BS300 is a modified polymer which made up of methanol and acetone.
BS300 is either orange-yellow or reddish-brown powder.
The normal dosage is: 0.3%-0.8% (BWOC) and it is not confined to this range in some particularcase.
Increasing additive dosage, it can adjust the rheology of the cement slurry effectively and reduces theconsistency.
With good high temperature resistance, it can be used within86℉-302℉ (BHCT).
Consolidates cement stones, enhances its compression strength and controls fluid loss.
With certain retarding properties.
Mixed with or without water.
Good compatibility with other additives.
