Alternative to Z-poxy?

[Tony Vega]

Can I use Loctite's 60min 2- part epoxy instead of the very commonly mentioned Z-poxy? I have a brand new box of it at my disposal and would like to use it to coat the inside of my SuperVee hull and wooden motor mount to strengthen if it got wet.

Thanks in advance.

I don´t know about that epoxy, but I installed everything on my Delta force copy with 30min epoxy(hot racing, hobbycity also sells it under their name), and it is holding fine. -it has 10minutes working time and it cures compleatly in 24hrs.

I would say that go for it

And I would use some fiberglass cloth also on the seam of that hull.

Brush some epoxy on the inside seam first, then add f/g cloth on that wet epoxy and brush eopxy on top.Try to get the air pockets out with the brush.

If you just brush the epoxy on the hull, that will work too, but it is not that strong as the epoxy with cloth.

Tony,

That should work fine. However, you will probably want to thin it out with some Acetone.

Denatured Alcohol works well for thinning also

Thin it with ALCOHOL. That is the prescribed solvent for epoxy. Acetone will work but not as well.

It may have been me but I have used that exact epoxy. When I thinned it with alcohol it reacted bad. Basically turned into a valcano. Bubbled up, foamed, melted the cup I mixxed it in. Again probably something I did.

Just a heads up.

Naw, come on. Alcohol will not react with real epoxy. Not sure what you had but...

[FastVee]

maybe you used too much hardener? -that WILL heat things up.

from what i have read if you thin with alcohol it speeds up your work time. so that makes sense that it heated up to fast. plus it will heat up faster in a small cup compared to a cup that has i bigger bottom

Where do you hear these things? I've been building boats, airplanes, etc. etc. for 50 years! NEVER has alcohol caused a problem with epoxy! Kinda like some of the other urban legends floating around I guess.

I looked at the article again and i guess i remembered it wrong . they where also talking about heating epoxy to thin it and i think that is where i got mixed up. any way here is the article its a good read. it also talks about the disadvantages to thinning with a chemical.

you loose strength by thinning but we are not worried about the strength as it is used to seal the wood

[Tony Vega]

You guys weren't kidding that the stuff I was going to use needed to be thinned. The bottle was brand new and too thick so I chucked it and went the the hobby store and picked up some 30 minute Z-Poxy. All is good now.

I have been using the Loctite but in a 5min setup and it works pretty good. I use it on joining and coating wood and plastic. "Now if i can only get that mixture right on those bigger batches."
