glycol charts

[Feargal Loy]

Does anybody know where I can download charts for Mono Ethylene Glycol, Propylene Glycol etc. showing concentration, eutectic point etc in relation to specific gravity?

I have tried asking some of our local glycol suppliers but they are unable to provide me with any data.

I have seen charts for M.E.G. showing properties in relation to refractive index, but being awkward I just cant help measuring the concentration the old fashioned way with a hydrometer!

Many thanks in advance for any help given.
