Prices look real good, I was just wondering if anyone here has tried using this brand of epoxy?

Works as advertised. Infusedwell. Great support and price seemed reasonable. Long working time though over 5 hrs. and 24 to demolding.
Knotty, with your 5 hour work time was that with any sort of heat source on the part being infused or was that just at room temp?
That was room temp and it was still pretty tacky after 5 hrs. For small parts it was a PITA to deal with. My biggest problem was trying to keep a good vacuum on the bag. I might try a part with a double bag. Inflate the second bag and put the heat lamps on it sorta like a little greenhouse.
5 hrs pot life will be good when we go to infuse the hull of our boat which will be about 125 sq yrds of heavy fabrics. Probably 20 gals of epoxy in one infusion shot!
I’d love to see a video and or picture sequence on a boat hull infusion. I was thinking of making a small model RC boat for kicks:D
Nice how the resin travels up hill like that.
What gives with the StarWars music on the second video LOL
Knotty, not to knock down the quality of this resin but if you are going to invest considerable amounts of $$$ in the building of a boat then I would suggest buying a resin specififally designed for marine use…even if you have to pay a premium price… Not that I have any knowledge in this area or anything , but it would be a real shame to go through all the effort and then have something go wrong simply because of the resin system of choice…
I would hate to see you in that position.
I still haven’t tested this “AeroMarine Products” epoxy resin system. I’m making some parts in a couple days with it. Think I paid $35 for 1.5 quart kit.
Werks said he used it and to his memory it was not real ridged when cured. I think for the parts i do that should be ok, or a benefit though.
Oh absolutely. I’ve been working with the designer who also specifically forumlates and sells marine quality resins. They just don’t have one with a low enough viscosity (yet) for infusing. That’s why I did the test last week with the Marinepoxy they sell.
Marine epoxies suitable for infusion are out there and rest assured we’ll use one. They’re not a whole lot different in their formulations though so most of what you read is just marketing babble.
The entire hull will be coated with a “barrier coat” which is another specially formulated epoxy coating called Interprotect 2000E from Interlux. I’ve used it before and it’s a fantastic product.
Are these picture flow times with or without flow media?
With. The fine stuff Werks sent me. More suited to smaller parts.
You guys might want to try this epoxy from Aero Marine Products out of southern California. www.jgreer.com He also sells on ebay under the name AeroMarineProducts. I emailed him and he got back to me today with a question i had. I asked if his epoxy works well for vacuum infusion. He said yes, but buy the " 1 hour pot life" epoxy kit he has.
He buys his epoxy from Dow, or Shell, or one of the major epoxy manufacturers. He won’t say which one.
1.5 quarts is $24.
1.5 gallons is $68.
6 gallons is $240 = $40 per gallon.
15 gallons is $585 = $39 per gallon.
I don’t work for the guy. just thought it may be worth ones while to test their epoxy and see if you or anyone likes it.
I just got a 1.5 quart kit with the 1/2 hour hardener. I will see how it works real soon.
The shelves are empty on his e-bay store.
I’ll be trying it out tomorrow, same epoxy with the #21 hardener.
Knotty, you might have had the wrong web page, i’m not sure. here is his ebay items…
http://search.ebay.com/_W0QQsassZaeromarineproducts
That’s just too weird. I searched earlier and there was nothing listed. Maybe down for inventory or somethin’! lol
Knotty, from what i read on their ebay listing, that PolymerProducts infusion epoxy kit takes 5-7 days to fully cure. And is supposed to be dry to the touch in like 8 hours or longer. Man… TOOO long.
I’m trying to order more epoxy from Aero Marine Products, but on ebay he only takes debit or credit cards, and i pay by cash. I emailed him and he WAY over priced it in his email to me, 4 times his ebay price. I emailed him back so hopefully www.jgreer.com ( his business will correct that for me. I’m hoping.
this is not uncommon for epoxy not be fully cured without post curing. room temp cure epoxies are usually 80% cured after 12-24 hours, which are ready for demold, however usually will take up to two weeks to gain all of its properties.
so will an epoxy cure to the same strength given enough time at room temp as one that was post cured?
