Composition of water based and semi synthetic coolant

Sir/Maam,
I just want to know the typical composition of water based and semi synthetic coolant.  I hope someone will respond.

I recommend reading METALWORKING FLUIDS 2nd Edition, by Jerry Byers for an introduction to the topic.  From page 140:

Sufonate base                    5.0

Alkanolamide                    15.0

100/100 naphthenic oil     15.0

Amine borate                      6.0

Triazine/pyridinethione       2.0

Water                                55.5

If you need more help, look to our Directories for formulators.  They can help as to recommended components in a basic formulation.
