The Best Glue For Binding Plastics

30.03.2016

Avoid a sticky disaster with our helpful guide to choosing the best glue for binding plastics together! Plastics are a notoriously tricky material to bond together with glue, particularly Nylon, Teflon and PVC. As a non pourous material with a smooth surface, it is easy to appreciate why they are so tricky to stick together, after all, the glue has nothing much to grab onto!

So next time you are working with plastics and need to glue them together for some reason, refer back to our handy guide to avoid getting into a pickle and sticking your fingers, (or the wrong surfaces) together...

  1.   Superglue

If you are looking for a fast fix, a good quality superglue may be the answer, however it really depends on your project. If you are planning to stick hard, rigid plastics together, this type of glue can be quite effective, however it is important to note that when gluing more flexible materials, superglue, which has a tendency to be quite rigid itself, can break apart as it is often too rigid to cope with any movement and remain stuck in the long term.

It is important to note that superglue should never be used on acrylic surfaces as it causes a chemical reaction which will damage and corrode the surface of the acrylic with a cloudy looking, white ‘burn’ mark.

The small application tip makes superglue a  great choice for intricate projects, however it is essential to take great care when using this type of glue as it is alarmingly easy to glue your skin to the surface of an object!

(Yes, I am talking from experience).

  1.   Hot Glue Gun

If you are planning to bond Nylon, a hot glue gun may well be your best choice and you will find this method works well with most other plastic surfaces too. The glue sticks themselves are made with various plastics, so it stands to reason that they are a good option for bonding the same material.

The down side of glue guns is that they can be a little messy unless you are familiar with handling them and there is always the danger of injuring yourself with the hot glue which can be tricky to handle, making it generally unsuitable for intricate, or delicate projects.

  1.   General All Purpose Glue

It is vital to leave an all purpose glue plenty of time to set, (i.e. overnight), but providing you are patient, this type of glue is a great choice for binding plastics together. (Don’t be fooled by the fact that it does not appear to stick at first and the surfaces still slip about). Take care to position the surfaces exactly where you want them, then leave them in a safe and secure place where they will not be disturbed overnight. By the morning they ought to be glued together splendidly.

Carry Out Your Own Tests Before Commiting!

Hopefully our tips will provide you with a great starting point for identifying the best glue for your particular project or application, however it is always sensible to carry out your own tests on materials to establish the best product for the materials you wish to adhere.

 Good luck!
