Bondic Liquid Welder

Bondic Liquid WelderKnown as the world’s first liquid plastic welder, Bondic liquid welder might look like a tube of super glue, but it’s far easier to apply and use without those loopy fumes. It’s actually a liquid plastic that remains fluid when applied until you hit it with a blast of UV light for about four seconds. That hardens it into a rock-hard plastic that can be sanded and finished so your repairs don’t stand out. It seems a lot less finicky than glue, and it will never dry out if you forget to cap it. This Bondic Liquid Welder should make repairs of all sorts of items easier.

The liquid is applied via a needle-type applicator, to items made out of materials including plastic, metal, fiberglass or wood. It can then be worked with until users have got everything set up the way they wish. They then just shine the light on the liquid for four seconds, which is reportedly all that’s required to cause it to harden.

Along with simply joining things together, this technique also allows successive layers of the plastic to be laid down one on top of another, in order to fill gaps. Once a gap is filled, the hardened plastic can be sanded, polished or painted as needed.

Bondic’s creators stress that you actually need to use and think of it more like welding than gluing, but it can adhere to wood, plastic, and even fabrics, through a process where you slowly build it up layer by layer (as needed for strength) not unlike 3D printing.
