A friend told me about a very thin resin that was like water, it is made in Germany. This is all he knows about it. Does anyone know what this is and where to get it?

Might be stuff called Poly C that Dave03B told me about.

Hopefully he will appear soon and post the link.

Pegasus -

Have you tried EZ-Lam from Aerospace Composites? It has a very low viscosity at room temp and is about the same as water when slightly heated. I never found out who the manufacturer was (I went through something like 10 gallons and was looking for a lower bulk-buy cost) but rumour had it is was from Germany.

Is this for laminating or casting?

I think it's called Epo-Thin by a company named Buehler (germany)
They have a US office: (see below)

PRODUCT NAME : BUEHLER EPOTHIN RESIN

Hi Pegasus, yes, I have heard of a substance like the one you describe.... the only one I know of like that is [link=http://www.rcworld.co.uk/polyc.html]PolyC[/link]

There was an article on this stuff (under a different name) done in the UK model mag, RCmodelworld. Its a lightweight alternative to epoxy glass. Seems very good although I have as yet, no first hand experience using the product. I hope to trial it soon on my GP Patriot.

I have not tried the EZ-Lam I usually use proset, its it the same viscosity as proset? From what I understand you bag your glass or carbon into the mold then a valve gets opened from the opposite end of the vacuum and it wicks the resin through another tube, sounds like a good way to may parts even lighter. I don't know if this Poly c is what I am thinking of I think this stuff I was told about uses a hardener, I will look into it and Epo Thin also.

I'm not familiar with Proset, I got out of the composites biz (making Swift race cars and some composite F-1, F3E, and Q-500 R/C models) before the resin injection method came along.

There might be better resins now, not sure. EZ-Lam is really intended for traditional wet layup/vac-bag methods. In my experience it can also be thinned quite a bit with isopropyl alcohol and since it is a faily low exothermic cure, it won't boil off and leave voids.

You may want to call George at ACP, he can give you specifics...

Your friend might be referring to MGS resin. By far the best stuff I have ever used. Doesn't contain amines, doesn't stink and it's working properties are awesome. I've used the 285 system quite a bit. You can mix and match hardeners for desired cure time too.

Don't forget, it's a pretty sky blue.

A good friend of mine used - Envirotex - to finish his scale warbirds. The first coat he mixed the two parts in equal amounts as directed then added an equal amount of denatured alcohol. It was the consistency of water and applied over 3/4oz fiberglass. After the first coat cured, he went over with a second coat, but this time only used 50% ratio of the denatured alcohol. There was hardly any sanding because the stuff is "self leveling" and it was tuff and easy to paint.

I'm playing with a new foam cutter and I will soon try his method on some sheeted wings. He did a Mesquito and a TBM Avenger that was quite impressive in the finish. I was surprised when he told me what he used.

I guess the epoxy resin you are looking for is the R&G LF+LF1 hardener, from german company R&G. It is aerospace quality epoxy resin, and available for modelers too. It's the best I have ever seen, very liquid, and laminates in extremely thin layers and cures as hard as glass. Unsure about the URL, though. They have a superb catalogue as well, plenty with all hints for our hobby, from moulding to laminating.

Found it !

Greetings,
Nicolas.

Thanks guys I will look into these.
Nicolas that may be the one I will have to get a sample.
Jet flyer I think the resin you are talking about is for finishing, it may be different than the resin used for lay ups, but will check it out too.
Mluvara, I have herd good things about this stuff too, is it better than proset?
thanks
