Bondic liquid plastic, UV cured in seconds

I ordered some of this stuff:

Looks really exciting. We'll see how it lives up to its hype. I'll try welding my fingers together...for SCIENCE!

Try it out in that bright California sunshine, should work terrific.

Taylor's been using UV-cure urethane varnish for at least 15 years. They hang 6 or 7 or 8 guitars in a booth that looks like a Star Trek matter transporter, hit the switch, 30 seconds later, done.

Dental work too. Some of my chompers are fixed up with UV-cured acrylic. It's fun when my dentist Dr. Larry puts on mad scientist glasses and shoots the ray gun at my latest repaired tooth, woo - hooo ! No more mercury for this mad hatter, never again.

My Bondic arrived. It's really, really interesting. First I used it to repair a fraying phone charger cable. Cures very quickly (3-4 seconds) and feels quite durable when set.

Next I created the little "snowman" sculpture you see in the photo. It's interesting to cure it as you squeeze the polymer out of the tube. You can see and feel how quickly it sets.

And, for an even more intimate look, I bonded, as promised, my fingers together. I could feel the polymer set very quickly with the UV light. But more to the point, I learned this is an exceptionally exothermic reaction. That small droplet I put on my finger, about 2.5mm in diameter, got hot enough to make me say yowtch! Felt like catching a drop of hot glue. And, in fact, the adhesion was about similar in strength to hot glue.

The snowman I made is remarkable for its properties. It peeled easily off the Post-It, meaning it's adhesion is low (I think hot glue would have pulled more of the fibers off the paper). It's flexible, and has moderate shape memory (not as flexible as hot glue, but not brittle at all--can't break it.)

And it's extremely strong! I couldn't pull that snowman apart--it required two pair of pliers and about 15 pounds of force. The snowman's neck (the thinnest part) was 1.2mm.

The literature says it's ok for use as insulation for up to 50cAC RMS, and 120v DC.

Hope you enjoy the review. This is a material with a lot of potential.

The resin must be similar to the stuff that is used in windshield repair. It uses UV, also.

That's pretty interesting.

I wonder how it does on dissimilar plastics?

Is the resin like they use in 3D printing?

They seem to have a UV-cured product for every application, dissimilar surfaces specifically mentioned.
