So strong it’s almost magic

Polycarbonate glue: The ideal adhesive for many plastics

You may not be familiar with the term polycarbonate glue, but you’ll soon find it indispensable for repairs around the home and office. It’s the go-to adhesive for most hard plastics.

What is polycarbonate glue?

Super strong and impact resistant, polycarbonate plastics are used in many every-day items, for example safety goggles, electronics like computers and smart phones as well as auto parts.

When you need to make a repair, it’s vital to use a polycarbonate adhesive to ensure compatibility. Typical household glues will not work.

The most common types of adhesives designed for bonding polycarbonates are super glue and epoxy. Super glue containing cyanoacrylate and specially formulated for plastics is recommended.

Polycarbonate epoxy is a suitable alternative. The advantage of epoxy is that it can fill rather large gaps. It forms an extremely hard bond once cured. Most epoxies can also be drilled and sanded, and they will even hold a screw once cured.

You’ll find countless applications for these handy adhesives. 

Making permanent repairs with polycarbonate glue

Here’s how to make a quality repair:

  1. Ensure that the parts to be bonded fit tightly and are clean and free of dust, oils, or any other residue.
  2. Polycarbonate glue comes as a two-part kit, including an activator and the glue. Apply activator first to both surfaces, covering the entire area to be bonded.
  3. Allow the activator to dry and react with the surface for a minute or two.
  4. Apply the adhesive to one surface only. Don’t try to spread the glue, simply apply about a drop per square centimetre. Press the parts together and hold firmly for at least 30 seconds.
  5. Allow the repaired item to cure for about 8 hours for full strength.

It is recommended that you wear gloves when working with adhesives. If you happen to get some polycarbonate glue on your fingers, no worries! It can be easily removed by rubbing some cooking oil into the bonded area. This will start to loosen the glue. Gently start rolling your fingers back and forth to gradually peel the bonded fingers apart. Never pull them apart forcefully or suddenly.
