I've been noticing advertisements for this stuff for the last couple of years, although I see there are YouTube videos from back to at least 2015.
Somehow the ads have always seemed "too good to be true", but given the uses reported HERE and HERE, I decided to give it a try.
Breaking with tradition, I also decided to read the instructions before playing with the product.
In the cleverly pleated instructions glued to the inside of the case with some soft tacky stuff, I was surprised to find this comment:
I guessed that they're serious about this, because the instructions also list the website for the product as www.notaglue.com , complete with the red emphasis.Bondic® is NOT A GLUE and will not work like
one, the surface MUST be rough in order for the
fluid to grab onto the material when
Elsewhere, the instructions refer to the product as an "adhesive".
I'm not sure what that difference is supposed to mean, so let me explain what I found.
The first thing I did was to dispense a drop of the fluid onto a microscope slide, press another microscope slide on top of it, and cure the sandwich with a few seconds exposure using the LED provided in the kit.
That worked fine, and the two slides were firmly fastened together:
To test the strength of the bond, I then tried to twist and peel the two slides apart, expecting them to break.
But to my surprise, the slides separated without breaking, leaving one slide with just a faint outline of the adhesive drop, and on the other slide a thin disk of cured Bondic :
Continuing the investigation, I pulled out my finest forceps and attempted to separate the disk of Bondic® from the slide to which it was attached.
Again to my surprise, that worked very easily. The cured film pulled right off the slide, feeling very much like removing one of those protective films that come on shiny new purchases.
That flexible film thickness measured as 0.0015" by micrometer.
I also dispensed a drop on a paper index card, hardened that, and was surprised to find that the drop was not very flexible and could not be cut by pressing my pocket knife through it. Pretty tough stuff!
Finally, I clipped the head off an insect pin, put a small drop of Bondic near the end of the pin, and then, working under a dissecting scope, held the pin by hand in position against the abdomen of a small fly and cured it. The biggest difficulty I had with this step was squeezing the LED module with one hand, hard enough to turn the light on, while simultaneously holding the pin in precise position with the other hand. I expect that a little more practice would take care of that issue.
Working on this subject, under the scope, I was pleased to see that the Bondic wet the cuticle of the abdomen and flowed smoothly around the small hairs, but did not spread quickly into far-away areas. It seemed to be just about the perfect viscosity for this application.
Summary is that Bondic is a UV curable liquid that hardens into a slightly pliable solid plastic that sticks to things mainly by mechanical interference. I expect it would be impossible to remove from any porous material, but it peels easily off glass. Re-watching the instruction videos, I have the feeling that some other product would be better for most of the featured applications. But for attaching holders to specimens, I expect this to become one of my favorite tools.
I hope this helps!
