PF-UHIB polyamine Inhibitor
Overview：
PF-UHIB is an amine derivative mainly used to inhibit shale from hydration and swelling. PF-UHIB can prevent water uptake by clays and provide superior cuttings integrity. It can effectively inhibit shale or gumbo clays from hydrating and minimize risk of bit-balling.
Characteristics：
Inhibit shale and cuttings from dispersion;Reduce risk of bit-balling;Maintenance of pH 9~10;Good Tolerance to common contaminants such as cement, hard water, CO2 and etc.
Special for HEM deepwater system，Temperature：≤200℃"
