JEFFADD® MW-760

• Easily Formulated
• Low to mild staining on aluminum
• Inherently low foaming
• Low cobalt and copper leaching
• Source of alkalinity
• Good pH buffer in water-miscible metalworking fluids

• JEFFADD® MW 760 amine can be used in water-miscible metalworking formulations. This amine should be added in combination with other water-soluble components. For formulation into emulsifiable oil and semi-synthetic formulations, emulsifier package should be adjusted. For some formulations containing a sodium sulfonate as the primary emulsifier, formulation viscosity may increase. We suggest adding in a glycol ether to help reduce the viscosity.

Linear Polarization Corrosion Results: Test Method: Probes are submersed in a 5% dilution of metalworking fluid. A constant current is placed on the fluid and corrosion rate (C.R.) is measured over time. The test is run for 24 hours.

Linear Polarization Resistance (LPR) Corrosion Test Chart (50°C for 24 Hours with Al 7075 and Al 6061)

• For JEFFADD® MW 760, highest corrosion rates are observed in the first hours of the test and passivation is achieved in about 2 hours.
• Formulation containing MEA shows much higher corrosion rates compared to JEFFADD® MW-760 and takes a longer time to achieve passivation.
• Lower staining is observed on probes for JEFFADD® MW-760 formulation compared to MEA formulation.

Ferrous Corrosion Inhibition

• Less amount of corrosion observed on formulation containing JEFFADD® MW-760 amine.
• No corrosion observed at 1.5% dilution of concentrate formulation.

• JEFFADD® MW 760 amine can be incorporated into a formulation with the addition of an alcohol. In this case, Dodecanal is used.
• Addition of 6% glycol ether for JEFFADD® MW 760 amine was added for comparison to MEA. Viscosity of JEFFADD® MW-760 amine was at an acceptable viscosity without the addition of glycol ether.
