Thermal degradation of Polyetheramines
« on: October 11, 2015, 09:58:08 PM »
We use a polyetheramine in a two-part epoxy. Everything I read (and the supplier) tells me to keep the polyetheramine (similar to Jeffamine D230 - Datasheet) at room temperature. Where can I find more information on chemical interactions of polyetheramines at temperatures above ~40C with air/moisture/other chemicals etc.?
I know the product we use is somewhat degraded if its heated above 40C, but along with that, it changes color (to straw yellow) and gives off stronger formaldehyde-like smells.
Our supplier is telling me he doesn't know what happens if you heat it, other than it degrades.

Youre smelling what was used to make it.  You can answer your own question with thermal gravimetry.
