Product Description

THESE SPECIAL FEATURES MAKE THIS PRODUCT SO SUCCESSFUL

NaMBT is supplied as a 50% aqueous solution and is used in formulations containing water and glycol. Upon application, it forms a thin, adherent film on metal surfaces that reduces corrosion of copper and its alloys while minimizing the impact on heat transfer. NaMBT also limits the catalytic oxidation of glycols, which can lead to acid formation and increased corrosion. The product can be combined with common inhibitor systems and is effective at relatively low concentrations.

Corrosion inhibition for copper and copper alloys via the formation of a protective surface film
Reduces the catalytic oxidation of glycols in cooling and antifreeze systems.
Compatible with common corrosion inhibitor systems (e.g. benzoate, borate, silicate, nitrite, molybdate and phosphate).
Effective at low concentrations, supporting economical use
Liquid form enables easy handling, dosing and dilution in industrial processes.
Soluble in water, glycols and alkaline media.

THE MOST COMMON AREAS OF APPLICATION

NaMBT is used in water-based and glycol-containing systems where copper corrosion needs to be controlled. Typical applications include cooling circuits, antifreeze formulations, and metalworking fluids. It is also used in functional fluids to reduce the effects of oxidation and support system stability.

Cooling water systems, particularly closed circuits containing copper components
Antifreeze formulations based on ethylene or propylene glycol
Water-miscible and synthetic metalworking fluids
Glycol-containing functional fluids requiring oxidation stabilization
Aqueous industrial systems where copper corrosion inhibition is required
