    Does anyone have any experience or details on Ciba- Geigy epoxy?
    My local fiberglass cloth supplier wants me to get epoxy from them as well.
    They couldn't really give me many details other than to say it was a one to one mix. Just wondering if anyone knew how it performed.
    I'd need a really good reason to switch from what i know works well.

    Epoxy

    I like system 3.

    The gel magic I tested at FAU was found to be strongest in interlaminate sheer, and high velosity impact.

    We tested against several over the counter epoxies.

    Good reasoning!
    At one to one it definitely will have different properties.
    This guy has a lot of good info.

    I know a man in Oslo, Norway, built a could moulded sailboat with epoxy from Ciba maybe 20n years ago. The boat is still sailing. I think the quality is good enough. Usability and additives (and cost, of course) seem to be important.

    I've used it and didn't like it much. The viscosity is very high which makes it a hard job to wet the cloth.

    I can appreciate that.
    Can you reccommend any "quick cure" epoxies (60 minutes or less) that would be good for assembling parts?
    I don't want to skimp on construction, but it would be nice not having to wait overnight for moving on to the next step.

    West system 105 with 205 hardner @ 85deg F. (A 1mm film)
    Do not leave "en masse" at that temp. ( in pot) or you will lose it in 10 minutes.Epoxy is VERY temperature sensitive.
    If you have difficulty warming your shop to this temp. make a hot box.

    Would it be OK for couldmoulding?

    I'm going to have to play with the fast hardner some more.
    I've been using West for everything. It just seems that when I try to do a faster set, it still takes a good 12-14 hours to get to the point where it isn't to tacky to handle. I guess I will have to push the heating process a little more.
    In the past, I have taken some 30 minute model airplane epoxy, warmed the bottles in a water bath, and had it set in about two minutes.
    I think I need to set aside an evening for expirmenting instead of building.
    Thanks,
    Rob

    I thought Ciba-geigy had switched to the Huntsman brand name globally.Perhaps this impression is wrong but I think if you Google Huntsman+epoxy you ought to find many different epoxies,among these there ought to be something suitable.
