FAQ
Q1: What is the main function of PAC in drilling fluids?
A1: PAC acts as a viscosifier and fluid loss reducer, enhancing drilling fluid properties, stabilizing boreholes, and minimizing filtration loss.
Q2: What is the difference between PAC HV and PAC LV?
A2: PAC HV (High Viscosity) provides higher viscosity and suspension, while PAC LV (Low Viscosity) is mainly used for fluid loss control with minimal impact on viscosity.
Q3: Is Unionchem’s PAC suitable for both freshwater and brine systems?
A3: Yes, our PAC performs excellently in both freshwater and brine-based drilling fluids, with strong salt resistance.
Q4: What is the recommended dosage of PAC in drilling fluids?
A4: Typical dosage is 0.2–1.0% depending on the specific application and mud system. We provide technical support for optimal results.
Q5: Can you provide technical and regulatory documents?
A5: Yes, we supply COA, MSDS, TDS, and offer technical support for your field operations and compliance needs.
