Water Dispersible and Cationic Agent Emulsified Asphalt SFT-I for Drilling Fluid
General introduction
Water dispersible and cationic agent emulsified asphalt SFT-I is obtained after asphalt is sulfonated ,cationic agent is modified and then get them emulsified . It has the characteristics of small common dosage,excellent anti-caving effect,high temperature resistance, highly efficient filtration loss lowering effect.
