    Default UHU Super glue - Miracle glue or sham?

    Just seen an add on Telly for UHU Super glue that you get from a newsagent or Officeworks. I know TV advertising is 100% factual but the claims for this glue are very impressive. First they say its officially approved by the Gunnies book of records and showed two 7cm diameter steel rods butt joined with the glue. a crane then picked up one end and a car was attached to the other with the claim it can handle 4.5 ton?

    It showed it sticking anything to everything. It really appears far fetched, and if it was on late at night in an info comercial I wouldn’t look twice, but would the Gunnies book of records and Officeworks put their name to a product if it was a sham? Anyone used this glue?

    don't want to be picky but do you really mean 70cm diameter?

    Really? Says 7cm to me.

    Either way, sound dubious to me. Unless there is some other wierdo force in action, I can't see how it would work.

    Love to see them preparing the surfaces. Wonder how much cramping it needs?

    Growing old is much better than the alternative!

    very impressive. And the strange thing is (not 100% sure) but i think the ad on telly used the same vision of that car used in the utube vid I will be keen to see the ad again. If so, they are lying as they used different glue

    Notice how they are always gluing two rods together? I bet they are precision ground/lapped mating surfaces-not something you'd normally find needing glue.

    I don't know if there's anything special about that particular glue, but super glue is really good at sticking two matching surfaces together. At the end of the day you only need it to be a molecule thick as long as its bonded to each surface. The problem is that in the real world, there are rarely two perfectly matched surfaces to be glued, even fractures will have imperfections at the molecular level.

    It's good if you need to stick your fingers together

    I've used the glue, originally sold in an industrial market place as "Eastman 910", to repair broken (or torn) finger nails. After about 2 weeks, the joint would fail mainly due to growth of the finger nail. But usually by then enough of a replacement nail had grown so that the broken or torn nail could be clipped off w/o pain.

    The glue is sold here to turners for finishing pens, etc. (Usually a few ounces sell for less than $15.) There are many brands but the most notable is "Crazy Glue". It typically goes for about a dollar for two small (less than 1/4) ounce tubes.

    There was a Crazy Glue commercial where the mating surfaces were square. One piece was attached to a construction hard hat and the mating piece to a crane. Of course the bloke wearing the hard hat was lifted into the air.

    BTW - Acetone can be used to break the bond of the CA glue. This is especially useful when gluing fingers to eye lids.

    CA glue's first commercial use was as a liquid suture for field treatment of wounds in the Viet Nam War. Field medics would glue wounds together until the injured could be medivacced to the nearest MASH. CA glue is still used for medical purposes today.

    I used to glue small cuts and hacks in my fingers with orange CA until they healed whereupon the body's natural skin regrowth cycle would discard it.
