scotch weld 420 epoxy

[porthos]

what on earth would make appx. 16 0z. of this epoxy worth over $1,000.00?? what is so special that causes it to be so expensive??

[Polymath]

I went and looked on Amazon and that was for a 5-gallon pail the 16 oz was about $45 bucks. Still pretty steep.

Someone may have quoted you the US Military price and not the normal price.

[JonB_in_Glencoe]

you can get epoxy at the Dollar store ...for a dollar.

[Mytmousemalibu]

Sounds like an aviation supplier price.

[porthos]

guess i better double check!!

[varmintpopper]

Wouldn't want to fly in aircraft that used dollar store epoxy

Yes indeed, you can get epoxy not worth a dime for only a dollar.

[Milsurp Junkie]

Really depends on where it was used.

[farmbif]

good stuff, if you take a look through mscdirect there are many many different very specialized epoxies, and as mentioned above some are very expensive.
scotch makes some outstanding products to meet or surpass different engineering specs.

this place is a great source for bulk epoxy products for many general applications

With aircraft, it’s the certs that cost more than the actual product.

there are a couple other brands that I can't think of right now. I remember a buddy who had some project they took into his shop and had to buy some sort of special epoxy and it was crazy expensive like a couple hundred dollars for a box that was about the size of a half gallon of milk.

on an epoxy side note the bedding epoxy brownells sells in little packages. other less costly epoxies can be substituted and mixed with cabosil or microbaloons to make a paste any thickness you want. marine tex works real well.

I have had very good luck with Harbor Freight Epoxy and JB Weld.

5 min epoxy for 8$ for 3 oz.

Two ounces of JB Weld is $5.18, that makes 16 ounces over $40 bucks. The modern marvel plastics, glues and even steel alloys are expensive until the cheap stuff fails, then they seem like a good deal.

The dollar store near us is now a $1.25 store. Way to go Brandon!

I’ve been building flying model airplanes for over 50 years. I won’t use any brand of 5 minute epoxy on anything.

I dont remember the name but we had an epoxy at work for gluing carbon together for edm electrodes. It was very expensive but also had to be able to conduct the electric thru the joint. It was very expensive also. The specialty epoxies ( conductive, Higher heat ranges, grits to maintain bond, shock resistance.) can get expensive. Sham Bam way lock was another one I worked with 800* temp grit to maintain bond thickness. It is used mainly for installing turcite on ways when rebuilding machines. It also has 4 hour working time and 24 hour full cure time.

[Shawlerbrook]

JB Weld is a very good product. When you need something to do something and do it right do not use price as a measuring stick.

[fixit]

I share the disdain for five minute epoxies. Just reading the spec details will quickly tell you the accelerated curing comes at a cost, not to mention, I've had too many times where I mixed a batch of the quick stuff, and ran out of time before I could use what I needed! Give me the half hour stuff, every time!
