Sr, Asphaltic offers a superior molecular weight hydrocarbon compound of a sodium salt of sulphonate asphalt. It is black free, Flowing flake material. Sr, Asphaltic can be dissolved in water, The water, Insoluble portion is soluble in oil. This property gives sulphonate asphalt an excellent emulsifying characteristic. Additionally, It serves as highly resistant to temperature. The following concentration of sulphonated asphalt are recommended suitable for elevated temperatures high pressure filtration control 2. 0 to 6. 0 ppb 5. 7 to 17. 1 kg/m for shale stabilization 2. 0 to 8. 0 ppb 5. 7 to 22. 8 kg/m to reduce torque and drag 2. 0 to 6. 0 ppb 5. 7 to 17. 1 kg/m as an emulsifier of diesel oil 0. 8 to 3. 0 ppb 2. 3 to 8. 6kg/m asa substitute of diesel 2. 0 to 6. 0 ppb 5. 7 to 17. 1 kg/m
