I need a safe epoxy.
Our parrots are sensitive to toxins, especially those ingested by a
respiratory route. Think "canary" and "mine." Same concept.
FixIt binary putty is sold by Apogee for making rocket fin fillets.
It's usable on containers that will hold potable water and is labeled
"non-toxic." I still wouldn't use the stuff around the birds, but at
least I'm able to work in the garage without worry.
Anyone know of an epoxy like this available in a liquid form?
(Yes, cyanoacrylate is used on bird wounds where stitching is not
possible. It must be used with significant ventilation, and it's one
of those "risk/benefit" things that medicine loves to come up with.)

I guess my first question is, "What are you trying to bond together?"
Most of the slow curing epoxy that I have dealt with seem to have little
odor, if that is any assistance to you? I have some JB-Weld handy so
that's the first thing that comes to my mind.
WEST sells different hardeners. if you need more working time try a
slower hardener (intended for higher temperature).
working outside today, it's 50o, so I had plenty of working time even
with WEST 5 minute stuff (G5). pour some liquid fillets, what a snap!
There have been times when I've used West slow hrdner in a setup like
a double boiler only the bottom was full of ice & water. That slowed
it down a llot. The Aeropoxy has a much longer setting product that
costs much less than West. If you are glassing a 10" or larger tube
and you want to vaccum bag it, time is against you.
From what I've read, Aeropoxy is stronger but neither one is weak by
Anything that the instructions say needs ventilation I can't trust in
the house. I'd swear that JB-Weld says it requires ventilation, but I
don't have any more. Could you check the packaging? I tried googling
it, but I couldn't find it.
First I'd get rid of the birds. I would not trust the "non-toxic"
label. If you want non-toxic, use kindergarten paste. There is a
wide variety of epoxy resin and some are worse than others. Some
people develop a sensitivity to epoxy resin, so the issue may be
hypo-alergenic, rather than actual toxicity. It depends on the person,
products, and exposure levels and patterns. I've heard horror
stories. The only person I knew who developed the sensitivity was
George Cook. He had to build models one handed, so I imagine he
tended to get messy with epoxy and have greater exposure than typical
modelers. CA was the only thing that allowed him to continue building
I have been using WEST for 15 years so I am familiar with how it works
in most conditions around here. it surprised me though, last May it was
100+o outside in the back, doing some hot tub repairs it went off really
quickly. from liquid to gel to solid, in like 2 seconds, right before
my eyes, you could almost see the long chain molecules linking up ...
but you're the 3rd person in two days to tell me about Aeropoxy. so I
am going to check it out!

The Shadow Composites video set started out with Aeropoxy and that's where I
heard of it. Aircraftspruce also carries it. I read of the smell and heat
that epoxy generated and kept wondering if there wasn't something wrong with
Aeropoxy, because it didn't have either. We used West on a 10" tube project
in a very warm garage. We were able to mix and spread 5 'squirts', but 6
caused the bottom 1/2" or so to be wasted because it kicked off. And when
you're holding a paper cup with 1/2" of smoking epoxy,...
I have an African Grey, about 17 years old now. 'Had her since she was
about 1-1/2. There is no way I "get rid" of her, she is a family member
and my kids know they will continue to be responsible for her when I'm
dead and buried [I'm now 48, and if she does anywhere near her maximum
life expectancy of 80 years, she will certainly outlive me!]
I have a rocket shop in my basement (actually I rent a second floor
apartment in NY, but have a basement room as well).

corners to provide full-spectrum light when painting
this pull from below the table through the filters, combined with a pull
through the ductwork by the window fans, should give me a maximum face
velocity of over 100 fps, if I calculated it correctly (factoring in
drag from the duct lengths and bends).
the fan sets are independently controlled by variable speed DC motor
controls [Pulse Width Modulation] so that I can tune the face and
downdraft velocity according to the application (composite fabrication
AFAIK this approaches or meets OSHA standards for paint spray booths,
although my intent is to use it for epoxy amd acrylic paints only

along the horizontal axis, for painting and curing.
and then there's always Nitrile gloves, face mask and eye protection.
not too shabby for someone in rocketry for about a year, eh, Ray?
I'll be putting up a website with photos as I get further along.
Nice to see some fellow bird owners among the RMR crowd. I have a 14
year old severe macaw. The only solution I have found is to keep the
bird and epoxy in separate buildings. Besides he likes to help way too
visitors always ask me if she can "talk". I say, "Of course! She talks
but she also talks Microwave, and always answers the telephone first! :o)
the really cool thing about birds is that you can have a conversation
with them from the other side of the house ... especially if the windows

she went from being an "Eric" to an "Erica" overnight!

You know, that's not a bad idea. The garage isn't heated, so venting
on a really cold day might be tough. Then again, on a really cold day,
you couldn't work with an epoxy in the garage anyhow, even with a

Why is it that parrots simply do not understand the concept that
everything in the universe is for them to chew on?
Except fresh food, of course. It's gotten to the point where, to get
fresh food into the one bird, she puts the food into one of her old
purses. When the bird eats the food, she scolds the bird, which simply
encourages the bird further.
Yes, it's an African Grey, and yes, it's mine. I really shouldn't
laugh when the bird chases my wife down the hall, nipping at her
heels. Laughter encourages the bird and annoys the wife.
