Fluid Loss Agent CP-8
Fluid Loss Agent
CP-8
Overview:
CP-8 is a white powdery solid formed by the reaction of acrylic acid and acrylamide. It is suitable for various drilling fluid systems, has good compatibility, can significantly reduce the fluid loss of drilling fluid, and excellent temperature resistance and salt/calcium resistance; It has low dosage (0.2-0.3%); and no pollution to the environment. CP-8 is not also applicable for polymer mud,and all types of water-based drilling fluid system. The highest operation temperature of CP-8 in drilling fluid could be 150℃.
