Evan's NPG-R coolant is propylene glycol
base?
"""
Yes. That's what the "PG" stands
for.

Hi
Marvin,
NPG is supposed to be
Non-aqueous Propylene Glycol.
NPG+ is "a non-toxic
blend of glycols rather than just propylene glycol". It would appear
that there is some ethylene in the NPG+. Here's a Q&A
from the site:
| Question: |
When should NPG+ be used instead of NPG? |
| Answer: |
NPG+ is preferred to NPG in all cases except where the ingredient
ethylene glycol is specifically prohibited (e.g., use at certain race
tracks).
|
NPG-R doesn't have that much info on
the site, and they don't specifically say what's in it. I recall the
bottle saying that it should be handled and disposed of as you would standard
anti-freeze.
Now you've got me curious, so I'll
email Evan's and ask.
Cheers,
Rusty (getting a handheld belt
sander for cowl shaping duties)
