Cohib A for Lubie Lube Coolant #325

Lubie® Cohib A is a formulated additive for reconstituting the cobalt inhibiting effectiveness of Lubie 325. Adding Lubie Cohib A will replace the depleted inhibitors used from the original Lubie 325 solution.

When replenishing your Lubie 325 solution we recommend the removal of as much of the machined metal fines as possible. The cobalt in the carbide fines will attach themselves to the Cohib A and reduce your tank life. If you have a filtration system now is the time to clean or replace the filter. If you use a settling tank now would be a good time to clean the sludge from the bottom.

When cobalt levels approach unacceptable levels, the solution turns purple, we recommend adding 0.5% Cohib A to your system and allow it to circulate. Then recheck the concentration with a refractometer to make sure you have the proper amount of inhibitors. Generally a 5% solution of Lubie 325 will reduce cobalt leaching to an acceptable level. See the refractometer readings below.
