CARBOQUAT MW-50

CARBOQUAT MW-50
Didecyl Dimethyl Ammonium Carbonate/Bicarbonate
Preservative for Metalworking Fluids and other Industrial Uses
Microbiocide and Corrosion Inhibitor for Oil Field
EPA Registered: 6836-323
Carboquat® MW-50 is a preservative that can be used to inhibit bacteria and fungal growth in
metalworking fluids and related fluids like hydraulic fluids and compressor oils. This microbiocide
may also be used to control bacterial and fungal growth in oil field and petrochemical flood water,
subsurface injection systems, such as secondary, tertiary oil recovery systems, tar sand and oil
sand and shale oil recovery, oil and gas fluids including drilling and packer fluids, hydrotesting
operations, pipeline pigging and scraping, oil and gas pipeline and tank maintenance and
preservation of fuel systems and fuel associated waters. It may also be used for slime control and
sulfate reducing bacteria in oil field water flood systems. Carboquat MW-50 aids in the control of
bacterial and fungal growth in paints, petroleum products, decorative coatings, industrial cleaning
solutions, and related products in aerosol cans. This multifunctional additive is also a highly
effective anticorrosion agent and an effective emulsifier.
Carboquat® MW-50 is a non-corrosive microbiocide that exhibits all the benefits of a quat but
does not contain choride. Carboquat® MW-50 provides an excellent thin film forming effect on all
metals and has good biodegradation with no bioaccumulation.
