- Suitable temperature: 25℃ ∼ 150℃ ( BHCT ).
- WH-2 is a free flow powder, non-poisonous, non-odor, and non-corrosive.
- WH-2 can confect different density dusting agents among 1.0 ∼ 1.9 g/cm³, it also washing the wall of well effectively.
- WH-2 can displace and flush mud efficiently, and prevent the contamination of cement slurry and mud.
- WH-2 has good compatibility with cement slurry, can dilute cement slurry effectively and improve the performance of cement.
