KR> Aeropoxy

[John D Cromwell]

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 Vinylester.  But it was easy to work with and burns down into it
self ...  I thank I had 2- 2 liter bottles of Resin on hand when I
started gluing my wings but that has been along time ago...

Happy New Year!

KR> Aeropoxy

[cruz...@frontiernet.net]

 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 with the older type 
Rand resins ,I always seemed to have extra resin gone to waste.  Also is the 
one hour hardener enough time to wet out one layer of glass? I'm thinking it's 
plenty of time with this lower viscosity type resin.

KR> AeroPoxy and Micro Mixture

[da...@windstream.net]

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 it to grams and zero it.  Pour in as much 
resin as you think you will need.  Multiply that weight by 1.27.  Pour in the 
hardener until you reach that weight.  Stir about 100 strokes and you are ready 
to use the mixture for whatever you wish.

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 only lost a little

[ttcse/Tom]

Hi John,  Let Me try it. 
 
Let me try it.  I've been a member of composite airplane forums for years and 
have hundreds of dollar$ of Aeropoxy in a storage unit.  At least one 
contributing member of those forums has substantial work in the epoxy 
manufacturing and evaluating field. 
 
If low temps are the only issue, it is not ruined.  It's just waiting for 
appropriate temps to finish curing.   It doesn't spoil. 
 
Low temperature will slow and/or stop the curing process until the temp warms 
up to around 100 + something degrees.   Once the temps hit those temperatures 
it'll finish curing and developing it's max strength.  
 
(To exotherm is not  normally a good thing.  You get this from an excessive 
quantity of mixed goo and the stuff can actually get hot enough to 
self-ignite.) 
 
Always a possibility is to wonder if you mixed the ratio backwards.  Rather 
than x-amount of resin and y-amount of hardner,  you did y-amount of resin and 
x-amount of hardner.  
 
While Rutan taught composite guys to mix for at least 3 minutes, scraping the 
sides and bottoms of the cup and all,  I'm aware of many guys who mixed for 
much less than Rutan recommendations and flew their airplanes for years. 
 
I'd say, get your temps up and see what develops.

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 
temp dropped to around 64 degrees F, now 2 days later the resin is still tacky 
in places. Have I just ruined the lay up? I used Aeropoxy PR2032 with PH3660

Aeropoxy doesn't cure very fast below 70F, and certainly not in the lower 
60's.  Heat it up to 78F or so and it'll probably finish curing in a few 
hours.  The tacky places you found are probably thinner areas where there 
wasn't enough volume in one place to go exothermic and warm the stuff up to 
the point of curing.  Trying warming it all up, and I'll bet it'll be fine. 
But if it's been above 75 or so for days and is still tacky, you probably 
have other problems as mentioned by Ron.  Aeropoxy doesn't usually have any 
kind of tacky film on the surface though.

KR> Aeropoxy

[Ronald Piekaar]

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 
left you with a few localized problems rather than a generalized 
problem. Try wiping the tacky areas with lacquer thinner to see if 
those areas are completely uncured or if the tackiness is merely a 
surface anomaly. If the areas are completely uncured I would suspect a 
mixing problem which would require a thorough cleaning (lacquer 
thinner, MEK, etc.) and patching of those areas. If the problem is a 
surface problem and the area is cured below a thin film of surface 
tackiness, clean the film thoroughly and you should be good to go. I 
would then call tech. serv. for Aeropoxy to prevent any further 
occurrences. Good Luck.
Regards,
Ron Piekaar,

Yep, happens all the time, especially with aged hardener. It has
something to do with being exposed to oxygen. It does not affect the
properties and is still good to use. Some do not like to use it in
structural applications just to be on the safe side. However, I have
used it in many instances and have seen no adverse effects.

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
just did not continue to use it because it didn'tseem right. I used West
Systems and am just guessing it would be the same cause.

If you're considering trying another brand of resin, have a look at MGS. Wicks 
and Aircraft Spruce carry it. It's a formulation designed in Europe for their 
Aerospace industry and is exclusively used in Diamond Aircraft (Katana). It's 
of very low toxicity, cure times are adjustable, has excellent wetout 
properties and is very user friendly. I've used a few different epoxys and this 
stuff is my favourite. It just works every time

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 %

I used it for the majority of this airplane and never had a problem with it.

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

Hay guys. I had the same problem and have had it off and on several times. How 
humid is it? I called aeropoxy and they said to try one trick. Take a rag and 
put MEK on it and and lighty wipe the surface. When it won't get hard because 
of mosture its called blushing. I don't know if age has anything to do with it. 
But call them to be sure or try a spot thats not important. One thing i found 
that works good is to build a tent over whatever your working on after the 
layup and put one of thoes electric oil filled radiator heaters under the tent. 
No open flame and you can regulate the temp. I've hade it up over a 100 
degrees. The aeropoxy people said the hotter its cured the more restant it is 
to heat after its cured.Anyway hop that helps.

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.

Larry:

Underwood may be shooting you straight.

When I worked for AeroJet in Sacramento they were winding 2nd stage "Peace 
Keeper" motor cases with "Pre-preg Kevlar Filament Roving"   The most importent 
reguirement was that it be conditioned in a 20% RH environment after being 
prepreged with Resin because moisture levels above that lead to delaminations 
in the wound cases.. That ment a humidity controled environment which was very 
expensive to do with refrigeration.   I inquired as to what the maximum 
temperature was that the roving could be continuously exposed and was told 150 
Deg. F.   I determined that in Sacramento if it were stored at 135 Deg. F we 
could keep it below 20% RH. because the 99% design wet bulb was 71 Deg. (if I 
remember right in Sacramento)  We had to control the
absolute humidity in the winding area to 63 gr. of water per lb of air and the 
winding was heated to with "Heat Lamps" to a point where the resin matrix was 
activated and the roving would bond together.  I am not  knowledgeable of  the 
system details as much of it I think was classified and may still be.

So  in short humidity levels can have a huge impact on composit resin behavior.

In short I suspect what  A. Underwood says may well be true and his anecdotal 
evidence seems to bear him out.

The problem with Kevlar layups absorbing moisture is a Kevlar problem, not
an epoxy problem. That kind of moisture absorbtion has caused delamination
of Kevlar parts on airliners due to freezing, and hence, it's fall from
grace in even non-structural parts in the aviation industry.   Don't even
get me started on Kevlar.  Although it makes a dandy bulletproof vest, it
has virtually no use on aircraft.

I've been using some dark red Aeropoxy hardener for years now, and see no
difference in the new amber stuff.  If you can't get that stuff to harden in
98F degree weather, there's a real problem somewhere.  I lay up glass or CF
using Aeropoxy in the morning, leave it in the high humidity 110 degree
hangar, and fly it and/or sand it later in the afternoon...

Talked to a rep today and was relieved to find out had not damaged the gear 
leg.  Had searched the archives for this and found nothing, so here it is.  

Epoxy lay-up turning brown from being too hot does not ruin the lay-up.  The 
rep from aeropoxy said that the epoxy can oxidize and that it is actually 
common.
