Epoxy

It really depends on what you want to do with it. I've used two component water based epoxies with success on interior surfaces. The so called one part water based epoxies are basically just paint. A lot of this env. friendly stuff is fairly new on the market, and doesn't have a proven track record. There's a lot of info and hype out there with a google search.

For any type of industrial application or where salts or chemicals are involved, I would go with the old school two component polyamide epoxy.

This is a good place to get info on some of the new stuff coming out. If you plan on using a lot of it, see if you can locate one of their commercial/industrial stores. A sales rep can make suggestions based on your particular needs.

Depends if you are competent. Do you know anything about surface prep?

Since you provide no useful information on the intended use it's impossible to give any advice.

My crystal ball says you build boat hulls???????????????????????????

Conventional epoxies are only a problem if misused. If you thoroughly mix and cure the unneeded epoxy it's not a hazard, unless you eat it.

I like the old chemical resistant polyamide epoxy, it smells like almonds.

Well, that's the good stuff alright.

Unfortunately, when the OP keeps everything secret it's hard to help.

I'm pretty much done with Guests anyway. It's like everything is a flippin military secret.

It's like:

How much air do I put in my tire?

What color underwear am I wearing?

Don't take it personally Mark, but how can we help If we have no idea what you are doing???

Rule #75 is alive and well.

I know it. Let's not forget the, guest asks a valid question, we all make posts with what seems like possible solutions to the problem, guest disappears without letting anyone know if someones idea worked. I hate that. It's not an ego thing, I'm genuinely interested in what the best solution is to some of these problems. But, what the hell, I guess it is what it is. Looks like you're slowly getting back in the saddle.

Yes, as I've said before, If it were my site, it'd be perfect.

Old people don't heal as quickly as young'ns. I'm back at work tomorrow, probably part time for a week or two. Thanks.

Good place to start . Marine structures are hard on material . Iron / Aluminum /

Everything . What Guest would like to learn is , epoxy laminating hulls with something that is already a strong , proven construction epoxy , but is used in a different application : To be asolutely specific : Scothweld Epoxy . Concrete Epoxy . How will it work joining laminated beams together on an offshore marine hull?

One way to find out ? Build one.

No secrets - Concrete epoxy is high performance material , and should work.

Actually I buid airplanes . You can have one . Airplanes are not in the same environment as boat hulls . That's what I'm asking you clevar people for.

Check out Easy-Poxy, from Aircraft Spruce--Burt Rutan's choice at one time---Let us hear...C-Mac

Will do - Thanks - And you are all right - Unless you know what you're helping to build , as they say in nuclear physics class - sometimes a little knowledge is a dangerous thing.

I would contact a pvc water main pipe manufacturer and see what type they use,then contact the company that makes that. U.S. pipe,Harco ect. C-900 is usually the pipe used. The hydrostatic test for this pipe is 150 psi for one hour.So I would think the stuff they use would yield good results.

They do but it end up what purpose you are looking for. They have far less data in most case and is typical to any new product and if you will ask same question after 10 years I will say this is as reliable as old poisonous stuff is but it is environmental friendly

Go to www.epoxyproducts.com, and anyone with epoxy questions will find an answer, and a product to meet their needs. If you need more info, mail Paul, listed on the site, and he will take care of you. You'll spend a lot of time on this site. One of the best product sites out there!! Let me hear. C-MAC
