It is suitable for use in fresh water, salt water and brine-based fluids. PAC-R filtration control agent is stable to 300°F (149°C), non-toxic and does not require a biocide. PAC filtration control agent products are premium quality fluid loss control products providing superior performance to most other products in their class. PAC-R filtration control agent exceeds the European specifications for regular viscosity polyanionic cellulose.
