Epoxy for encapsulating cells (great DIY thread with photos!)

[scheek]

I'm not for sure, but kermitas maybe using epoxy to adhere the cell to backing. I encapsulated mine entirely. Make sure you are talking about the same thing.

Good luck,

Is this optical clear. it sounds real good . I didn't check out the price for 20 oz. if it's plable when cured it's good.

If I will have some free time I will also look at it - but for now it looks interesting.

That sound just like sylgard 182 sence it takes up to 24 hrs. to cure. and 28$ is a steel because sylgard is only 20 oz. Thanks for the english version.

I have a DVD that show's you how to do something like the vacuum but I don't know how to post alink . It is interesting. I some how have three of the same DVD. A normel hairdryer might do but just to be safe you should get a hotter one, Don't you think????

I just found at local producer something that can be very similar to Sylgard 184 : http://www.silikonypolskie.pl/?opt=shop&item_id=34 . Try to use google to translate into English http://translate.google.pl/translate...34&sl=pl&tl=en .

I send question to producer about how much it is similar to Sylgard 184/182.

1.1lb (0.5kg) cost around ~$28.

The radio control model planes have a plastic shrink covering that takes a heat gun to draw the wing covering very tight. Check with Hobby Lobby International, or your local hobby shop to see those. I think they just cost about $30.00. They also make a teflon coated small footed heating iron (Monokote brand) with an adjustable heat knob, too.

You are right.

And about the link - if you have it just paste it here. It will be not clickable but I am sure that everybody can copy&paste it as an address to web browser.

I think it's real good . I haven't thought about the Tedlar or EVA because I don't have the setup to do something like that.
I hope you can work it out. I don't know what the price would be so I hope it works for you.
I know a guy who made his own heat table with a vacuum in it also but I haven't heard from him in a long while.

(Look, I edited my post when you wrote your post.)

Maybe mormal hair dryer will manage to do that ? 375F is not so much...

I realy like your panel. It's very good. Sorry about the sylgard, I have been looking for other things that might do but so far I haven't found anything. I'll keep looking because I'd like to see something there that is cheeper then sylgard.

I also would love to see anything as good as Sylgard but cheaper. I am serching for it almost every day but with no success.

Now I started to think about those Tedlar/EVA foil and heat gun as it is on this movie at youtube.

Calculation is : to cover my panel (1 meter x 1 meter - it shoud be around 10 square feet) it tooks 10x$1.65 of tedlar foil and 10x$1.65 of EVA foil = $33 !!!!!!

Now I am checking pricing of heat gun...

Tedlar TPE foil : "Normally in production you would use a Clamshell or Bed laminator that controls all of the pressure and heat but for most a heat gun and ingenuity will have to do."

EVA foil : "If you are going to use Tedlar as your backing, you will need a way to use vacuum and pressure to sandwich the material."

What are your thounght on this subject ???

I'll show you a place where the sylgard is $36.87 a peace but you have to buy three of them if you go here.:Superior Essex. and go to the onling shopping then look for DC-184-1.1 Three of them comes out to $125.44
I do know how exspensive everthing gets. Here in my town I had trouble to get the lumber companeys to cut a size that I wanted for my first panel . I got so tirer of this I went out and bought a table saw to do it myself.
It seams tha everthing cost me extra because where I'm at .( Cheyenne , Wyoming) There more into wind generaters here.

Superior Essex is not so fine . They want me to buy minimum 7 sylgards and shipping cost would be then $290 !!! So they are even not competitive to simple eBay sellers : seller1 , seller2 .

It is not easy to find any elastomer as a Sylgard 184 replacement .
I started to think about Tedlar . I don't have any heat and pressure table but maybe using heat gun... http://www.youtube.com/watch?v=f1CJhwmMODs

PS : using this Tedlar (eBay) is it really needed to cover cells in front using EVA ?? Why everyboduy use it there (on front of the cells) ??
