REFLECTOR: EZ-84 epoxy ratio

[Darrell & Nora Kufalk]

Thanks for the info.  I didn't know Spruce sold this stuff. The catalog also
says the cure time @77 degrees is 3 days.  Maybe I'll see how it looks
tomorrow.

 

I think as the hardener ages it seems to cure faster.  The last layup I did
about 6 months ago with 1 year old hardener cured completely in less than 24
hours to the point that I could sand it.  

 

That's the hardener that's still in my pump.  At 1-1/2 years, it now has the
consistency of frozen ice cream.

Per the Aircraft Spruce catalog data sheet - mixing ratio is 100:44 by
weight and 100:47 by volume.  Sounds like you may have a different problem
than the mixing ratio.

My sticky stuff pump is clogged with old hardener and I'm too lazy to clean
it out right now.  I just need to do a small layup with some new hardener I
just received.  I did a test layup with a scale and I mixed it 100:44 by
weight.  It's still soft 24 hours later.

 

Who remembers the correct ratio by weight?
