New Fashion Design for Oil Jacketed Cooking Pot - Fluid Loss Control High Temperature Anti-saline – Taige

High temperature fluid loss agent        XBA-203L

Introduction

 XBA-203L is a high temperature fluid loss agent.

 XBA-203L’s applicable temperature is 60~150℃(BHCT).

 XBA-203L is resistant to salt and applicable to saturated brine.

 XBA-203L has a retarding effect and is suitable for high temperature and deep well cementing.

 XBA-203L slurry system is stable and has good compatibility.

 XBA-203L is liquid and only can be used through wet mixing.

 XBA-203L’s dosage need to be adjusted according to temperature, salinity and cementing requirements.
