􀂾 Cost effective viscosifier.
􀂾 Non-Toxic.
􀂾 Effective in low concentrations.
􀂾 Not subjected to bacterial fermentation.
􀂾 Treatments for freshwater and seawater fluids are generally 0.5 - 4.0 lb/bbl (2.85 – 11.4 kg/m3). Actual concentrations required will depend on the type of mud system, salinity, temperature and properties desired.
􀂾 Rapidly losses effectiveness with increase in salinity.
􀂾 Temperature limit of @ 225 - 250 0F (107 - 121 0C).
Consult MSDS before use and use personal protective equipment as advised.
CMC EHV is available in 25 kg (55 lb) polyethylene bags. All materials are stored in a dry well ventilated area.
