Intro: Bondic How-To - Repair Broken Glasses

Broken glasses are an absolute pain. Whether you are on the go and an unfortunate accident happens, or you are just at home and sit down without looking, breaks can happen anywhere. That is why Bondic is the best tool to have handy for any glasses mishaps.

Bondic® is the World's First pocket 3D liquid plastic welder that allows you to fix, fill, mold, and even build almost anything. It will only solidify when you cure it with the included UV LED light, so you control the drying time. Once the UV light hits, it only takes 4 seconds to harden with no pressure needed and it will not stick to your skin. Keep in mind that Bondic® is NOT A GLUE and should not be used like one. It literally is a welding tool that uses a unique formula to build new plastic around two objects instead of “gluing” two flat surfaces together. Think of Bondic® closer to that of a 3D printer, creating new material where it has been lost. Additionally, for Bondic® to stick onto surfaces, it needs to be rough to allow the Bondic® fluid to seep into the pores of said objects and literally “grab” onto them when cured. We always like to think of Bondic as like gripping something with your hands. If you are trying to grab onto a smooth surface it will be really difficult to do so. But if the surface is rough, you can get a much better grip.

Step 1: Roughen the Surface

Before you start, use a nail file and start roughening up both ends of the pieces you are bonding together. After that, take a knife and create vertical cut lines across the parts you just sanded. Bondic needs a rough surface area to be able to "grab" onto things when it cures, so the rougher the surface, the stronger the hold!

Step 2: Apply Bondic

Now that the surface area is nice and rough, you can begin applying Bondic.

Start off with a small drop and hold the two pieces of the arm together. Do not worry if you did not put the Bondic fluid in the right position, Bondic will only harden if exposed to the UV light, so you have lots of time to get it right!

Once you have the fluid in the right spot, shine the UV light and watch it harden in seconds!

Keep applying Bondic in small layers, roughly 0.5mm at a time. Bondic will always cure to itself, the bond is so cohesive that every layer you make will fuse into one solid piece, just make sure you are not curing more than the recommended amount above at a time because the light will not be able to penetrate through.

One trick to use to make sure it is fully cured is to simply tap the end of the light against the drop you are shining the light on, if the light does not stick then it is 100% hard plastic now. Keep building layer by layer (like a 3D printer) until you have created the desired shape. Do not worry if the shape is not perfect, you can fix this later!

  • Do not worry if you cured too big of a Bondic "blob" you can easily use a nail file and shave it down to the exact shape you want!

Step 3: Paint It!

If you are a perfectionist like me, you are going to want to paint over the cured Bondic material to match the glasses perfectly.

In this particular case, I just used black nail polish. Feel free to use any paint you have on hand, even a marker will work.

Simply apply a few layers of paint over top of the cured fluid, you may need 1 or 2 coats depending on what you are using.
