Default Epoxy is really crap for homebuilding

I hate to say it, but breathing that epoxy or some other substances
has burned out your olfactory nerves if you don't find Aeropoxy
objectionable. Although, I have used epoxies that smell like the stuff
in those 5 minute tubes. It;'s not that bad. And I just ordered a
different brand, hoping it will not have that amonia odor to it. And
my Aeropoxy has sat around for a while, and the hardner has turned a
deep red color, so all my layups are now deep red. I've read the
manufactures info on that, and they say that's a normal aging effect
of the hardner and dosen't affect the strength. But I wonder if it
make the smell worse.. hmm..


You must be hypersensitive to the amonia smell because the only time I
have noticed it to any degree is if I took a deep whiff from the can.
Even then it is not overly strong. Even my wife, who has the overly
sensitive nose in our household doesn't mind the epoxy odor. The red
coloration is simply an oxidation that occurs in the hardner over time
but hasn't caused any problems with the layups I have seen.

Clearly though, you don't like working with epoxy so my simple advice
would be DON"T. The fact that you don't like it though is not a valid
excuse for condemnation of all things composite or for degrading a
great designer who revolutionized homebuilt design and construction.


In the future if you hate to make a uncalled for comment, don't.

worked with epoxy for the last 10 years including Aeropoxy, E-Z Poxy,

part at all. *I will totally agree with you that Vinyl Ester stinks to
the high heavens but have never experienced any such problem with
epoxy formulations. *I can't even stand to work with completed parts
made using the Vinyl Ester but not so with epoxy parts.


I also can't agree with the Toxic comment regarding epoxy since it is
much less toxic than either Vinyl Ester or Polyester Resins.


Guess this is just another case of beauty being in the eye of the
beholder. *I rather enjoy working with composites and prefer them to
working with metals.- Hide quoted text -
