Got one of these a while back; not really impressed, but I think I didn’t use it as intended. The control panel of our stove developed a crack due to heat (yeah, “WHAT!”, but that’s another story), so I bought this to attempt to restore the control panel.
It worked for a bit, but failed under the stress of people using the control panel. I suspect it’s more for static patching than for anything that takes any kind of stress (i.e, think “clay” rather than “glue”).
I am with Bryane with this… I have also found it does not stick to all plastics. That is not surprising, I have encountered that before.
However, for hobbyist’s, it rocks. Finally, a glue that will not screw up a plastic windshield on a model! Just weld it into place and it’s set. It is also very clean, no drips and it won’t make your fingers sticky.
I also suspect it is very kid friendly, no smell and less chance of a mess… and with some experimentation, since it doesn’t stick to all materials, it might come off of mistakes easier, but that’s only on a case-by-case basis, no promises.
In my case I had a pair of office scissors that had started to break where the plastic handle meets the metal blades. Since the scissors were still plenty sharp, I didn’t want to trash them, so I glued them. The Bondic adhesive was easy to apply, but after a few days, it flaked off. I attribute that to the type of plastic, and the torque loading. Next, I used JB Weld Plastic Epoxy, let it sit 24 hours (Bondic is FAST trying, instantaneously fast) and the epoxy is as tough as nails. It’s good to know when to use the right product for a given job.
In general, for hobby use, go for it. For structural repairs, stick with a quality epoxy product.
Pro tip: This adhesive, like most others, works best with a roughened surface which is completely oil or grease free. Sandpaper and 99% isopropyl alcohol are good for surface prep.
Interesting insight from the Bondic website which almost hilariously offers the disclaimer in the URL notaglue.com that they do not claim to be a glue.
“Bondic® isn’t a glue, it has some adhesive properties but it sticks to smooth areas using a lot of surface tension rather than stickiness.”
Frequently Asked Questions | Bondic®
Please consider something with high tensile strength and sheer resistance for a item that will have heavy physical use. Epoxy is probably much better. “JB Weld” has an amazing 3000 lbs/sq inch. But it is gray color. It might be sanded and painted.
Fellow poster whitcha is very right - glues and even Bondic work far better if you do surface prep to roughen and remove all traces of skin oil and usually moisture as well (exception is there is a marine version).
