I built my KR2 wings etc., with Vinylester Resin but I had to do smaller
areas because it set up kind of fast. I used small wax free 4" paper
mixing cups and mixed the resin & hardener as needed for that area I was
glassing at the time. Would of been neat to have a one hour set up time
with
I am wondering how much Aeropoxy I will need for wing construction on my
KR2S. How much should I have on hand while laying up the fiberglass ? I plan
just one layer of glass at a time with peel-ply.Is there is a method to figure
how much to mix for a given area ? From previous experience
s nothing to do with your question.

I have a second layer of glass over the leading edge, and about 4 inches
past the main spar, and the wing tip has glass about 1 foot in word, over
the original dynel, can I put 3 quarter ounce glass, over the remaining
exposed dynel?

In laymans terms, if I was using one measured cup of resins, what would be a
good ratio for the hardener? in cup terms, 4 instance a little over a
quarter cup?

The ratio of Resin to Hardener for AeroPoxy is 1 part Resin to .27 part
hardener and this is by weight, which I forgot to mention before.
The ratio is the same no matter what you are using it for, Micro, Flox,
Fiberglass, Carbon Fiber. It has to be the same.
Put your cup on the scale and set
Sorry,still learnin how to use a web site, I layd up the wings,is the racial

First, you need to remember to change the subject when you are changing the
subject. Your question had nothing to do with "Wingspan". I almost deleted it
because I have read enough about wingspan.
The ratio for mixing AeroPoxy is 1 resin to .27 hardener. For sealing the foam

I don't know about Aeropoxy, but I had an old (?'08?) qt. of Polypoxy that was
about 1/2 wax that I put into a pot of boiling water for an hour back in
October. It turned back into clear liquid and has worked fine since. You
could
try it with the Aeropoxy, if it works, great; if not, you've
If kept covered, that should not have happened. I have had Aeropoxy for
over a year and it was still usable. I suggest you go here:

Can Aeropoxy, part A resin be rejuvenated if it has gelled? I know that T-88
can be brought back to use if it crystalizes by warming. Is the same true for
Aeropoxy resin or should it be discarded. About a third of the volume has
stiffened into a gel.
Resin and hardener were purchased
their airplanes for years.
I'd say, get your temps up and see what develops.

Hi John,
The usual suspects for uncured area of epoxy are inadequate mixing,
expired shelf life, surface contamination or incompatibility with
something in the substrate. Assuming none of these, the epoxy should
cure at 64 degrees as witnessed by the fact that some of it did which

I have a question that I hope has an easy answer guys. I put a layer of glass
on my starboard elevator 2 days ago. That night we had a power failure and the

Has anyone ever seen aeropoxy hardener turn deep red in color such that it
changes the mix's color from amber to red?
Wondering what happened there.

Matt,
Some where along the line I was told that it is from absorbing
moisture with age. I stopped using the stuff that had changed color for
anything structural and used it up for micro filler and such so it did
not go to waste. I do not know if it harms the integrity of the epoxy, I

How humid is it in your area? Has been real bad here and that will affect
your setup time. We have been running in the 90 deg and 90 %

The mixture ratios for ANY epoxy must be EXACT. I suggest that your

I thought MEK was used for polyester resins not epoxies but hey if it
works!?? I used an electric blanket over a plastic sheet on my layups when
necessary...wife wasn't amused.
