    Product Detail

    Product Description

    NP-1 is a multi-polymer composed of alkane sulfonate, alkyl ester, crosslinking agent. It forms nano-solid sealing material through special technology. The special functional groups on the molecular chain has strong adsorption ability, and strong adhesion properties. NP-1 reduces pore-pressure transmission by sealing pore throats and micro-fractures due to reasonable size distribution of NP-1 in muds. It can be used in various water-base drilling fluids. Its recommend dosage is 1.0 – 3.0% (v/v).
