Metalworking Fluid and Amines

Do you what are Amines? Even I didn't know until today. Recently I attended an evening seminar arranged by our Metalworking Fluid supplier. Like many others, for me the objective to attend the event was just to enjoy cocktail dinner. I am using their fluids already so they do not have anything more to sell me. During the presentations I heard this word "amines" quite frequently and I felt as if I am the most uneducated man in the group who is clueless about amines. Once back in the office, I did some online research and this skill builder from QUAKER helped me to understand a bit. I felt it will be worth sharing this information to those who are like me, unaware about amine facts.

An amine is a classification of organic compound that contains nitrogen, carbon and/or hydrogen. The ratio of these three elements defines the four types of amines: primary, secondary, tertiary, and quaternary. Amines are used in Metalworking Fluids to produce alkaline pHs (greater than 7.0) and provide buffering capacity. This ensures higher pH which is helpful in reducing corrosion and minimizing microbiological growth. Ideally MWF should be DEA free (Diethanolamine, a secondary amine)

As a user, this much information will help me to pretend to be highly knowledgeable in chemistry during the next event.
