AMPS (ATBS) POLYMER FLUID LOSS ADDITIVE
·High efficient fluid loss additive with high purity and low dosage.
·Applicable in a wide temperature range and has better high temperature resistance performance.
·Salt resistance and resistant to saturated brine.
·Stable with little free fluid.
·Not retarded, fast strength development.
·Excellent rheological behavior. It doesn’t require adding additional dispersant.
·Suitable for both water and dry mixed.
·No special requirement on the quality of mixing water and is soluble in cold water.

PACKING AND STORAGE
It is packed with 25kg bag. It can also be packed according to user requirements.
Normally used within 18 months after production. If expired, test should be done to confirm the quality. Store in ventilated, cool and dry area, avoid exposing to sun and rain. The height of stack should be less than 8.
