Alternative for Glue ?

    Has anyone tried out the new product called Bondic It's what Dentists have been using for fillings and stas as a liquid until you apply a UV light source. It's said to be 100 times stronger than Superglue and safer . Acording to their website, it looks like a good filler too. I have some on order and, unless anyone else has tried it, I'll let you know how it fares. It looks ideal for small fixings. Ray

    We have at least one dentist on here who has always said he doesn't use dental materials.

    Be interesting to see if this works.

    I have used UV-curing fly-tying glue for casting; it works well and doesn't go off until you want it to, and then it is cured instantly. It helps to use a clear silicon rubber so the UV can penetrate.
    It's also excellent for gluing glass and acrylic almost invisibly.
    I suspect it's a lot cheaper than the high-end dental stuff.
    The straps on my AFS Fireman bust were cast in flexible UV resin, which allowed them to twist without breaking.

    I tried it without success Ray. Perhaps, I didn’t apply the UV light correctly. The blurb claimed that it would set immediately but after several attempts it didn’t work and the piece I was attempting to glue on fell off.

    Perhaps others have had success. If so I would be keen to know their technique for using it.

    This kit has a UV light source at one end, and the liquid dispenser at the other, I have ordered one basic kit plus 5 refills for a cost of $57. If it works, I can see loads of applications, e.g. on their website they show the liquid coming out and instantly turning solid forming a solid tower of clear material ideal for filling larger gaps like Horse halfs in the larger scales.

    There are a number of terms that sometimes get used interchangeably. Cementing, welding, soldering, adhesive, gluing, and luting all have technical definitions.
    The light cured material dentists use is a resin. The term "cement" is misleading. In the past, dentists "cemented" crowns onto a tooth but the "cement" only locked the crown in place by filling in the imperfections of the tooth and crown. The correct term is "luted"as the "cement was neither a glue or an adhesive. The early resins, used for fillings, is a composite resin and used chemical initiators to harden the material, like we think of epoxy because of the two parts. This early material did not attach to the tooth or crown, a resin but not adhesive. The next improvement was to change from UV light cured resin to high intensity light cured. UV did not penetrate very far into the tooth or material and the use of visible light initiation became the standard. Chemically cured resin darkened with time where light cured is color stable. Today we have light cured resins that can be clear, colored, filled with glass,ceramic, or other resin. Again, we don't glue or cement crowns but the term "bonded" is used. "Adhesive bonding" is achieved by special surface preparation of the tooth surface or the crown surface via sandblasting or chemical treatment to get the resin to adhere. I don't believe you could use dental light cured resins to cement parts together. [There are dental materials that are powder/ liquid monomer/polymers that could attach to other plastics, if similar, because they are able to reactivate the surface.] Epoxy's are adhesives and are resins that glue things together on their own. Most surfaces, when using epoxy, need to be clean without any special surface treatment. On plastic models the cement we use melts (welds) the plastic and the two parts are fused together becoming one material. When you solder metals together the solder melts and adheres to both sides but does not melt adjacent two metals. Welding melts both sides.
    All that being said, the product in question is a UV initiated resin AND would need to be an adhesive too to hold items together securely.

    This one?

  9. Ray Stout Active Member

    No, very similar, but not that one. If you Google Bondic you can find the web-site and see for yourself. Ray

    I’ve not tried using as a glue but I found it worked okay to add skin texture to a Godzilla model I was working on. I’ve also used it to help fill gaps on plastic and resin models. I had a small issue with primer coating it properly but 2 coats did the trick. I’m still tinkering with it to see if I can use it to add hair texture using a fine brush.

    As soon as I get mine, I'll try that with a Pyro Gerald and report back here. Ray
