Fluid Loss Additives-OBC-32S

Short Description:

Summary OBC-32S is a polymer oil well cement fluid loss additive. It is copolymerized with AMPS/NN, which has good resistance to temperature and salt, as the main monomer, combined with other salt-tolerant monomers. The product introduces groups that are not easily hydrolyzed, the high temperature resistance is significantly enhanced, and the molecule contains a large number of strong adsorption groups such as -CONH2, -SO3H, -COOH, etc., which play an important role in salt resistance, temper...


Product Detail

Summary
OBC-32S is a polymer oil well cement fluid loss additive. It is copolymerized with AMPS/NN, which has good resistance to temperature and salt, as the main monomer, combined with other salt-tolerant monomers. The product introduces groups that are not easily hydrolyzed, the high temperature resistance is significantly enhanced, and the molecule contains a large number of strong adsorption groups such as -CONH2, -SO3H, -COOH, etc., which play an important role in salt resistance, temperature resistance, free water adsorption, fluid loss reduction, etc.
OBC-32S has good versatility, can be used in a variety of cement slurry systems, and has good compatibility with other additives.
OBC-32S has a wide application temperature, high temperature resistance up to 230℃, good fluidity and stability of the cement slurry system, less free liquid, no retardation, and rapid strength development.
OBC-32S is suitable for fresh water/salt water slurry preparation.
