Non-Toxic Epoxy Needed

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 thought aeropoxy doesnt contain MDA or something like that so it can be shipped as nonhazardous. I wonder if that would qualify?

Tai,

indicates that it might be toxic as well.
Then again, perhaps writing to some of these manufacturers might get me some assistance. Thanks for the idea.

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.

I use it. It might not have MDA but, it's NASTY. Bothers my skin more than West. The good news is that it gives you more working time than West at a lower cost.

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!

It's obvious. The parrot to the payload section...

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 any means.

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.

Nah. I'd have to make the payload section out of titanium. I've had one bird chew through wrought iron. Ok, so it took him a couple years.

Don't have the package but the tube says "Use with adequate ventilation"

I couldn't understand what epoxy 'smell' people were talking about until I used a brand other than Aeropoxy.

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 rockets.

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).

I have a project underway, about 2/3 complete and all materials on hand, to address the toxicity from fumes and composite particulates for my kids and I
[Note: Grainger item numbers shown]
(14) 5" computer-grade fans Air Flow @ 0.0 Inch Static Pressure 80 CFM
distributed below a 20" x 48" table surface, pulling air (top to bottom) through:
1. an expanded paint collector filter [6W749] 2. a three ply polyester ring panel filter [6B803], and 3. an activated carbon (disposable) air filter [6W738]
from the cavity below the filters, the air is pulled through approx, 10 feet of 12" round duct with 2-90 degree bends, out through
(2) shutter mounted exhaust fans [2C819] Air Flow @ 0.0 Inch Static Pressure 585 CFM
the table enclosure is plywood 3/4" ply back and sides, with a disposable liner paper [6W753] that rolls out to replensish
a 5/8" thick Plexiglas front that slides down to expose a 36" H x 40" W face to a 1500 watt Quartz heater for curing or dryimg
the cabinet is lighted from above with a double 48" flourescent fixture, and I will likely position a few small xenon fixtures in the front 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 vs. airbrush)
AFAIK this approaches or meets OSHA standards for paint spray booths, although my intent is to use it for epoxy amd acrylic paints only
o, and a side-mounted stepper motor will provide rotation of the rocket along the horizontal axis, for painting and curing.
and then there's always Nitrile gloves, face mask and eye protection.
:o)
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 much!!!!

visitors always ask me if she can "talk". I say, "Of course! She talks parrot!"
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 are open
we thought ours was a male for the first eight years, and then we started seeing eggs ... about 1 a month (which she would promptly eat)
she went from being an "Eric" to an "Erica" overnight!

Sweet!
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 space heater.
MIght have to look into that.

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.
