Glue for Plastic – Buying Guide & FAQs

What is plastic glue

Plastic lacks porosity and roughness, which makes it difficult for the glue to find anything on which to bond. That’s because different types of glues and adhesives either dissolve or don’t bond well with plastics. It will help if you have an adhesive that works specifically with plastic and the types of plastic you’re using.

How do these plastic glue work

These glue contain solvents that work when you push the glue out of the tube (the solvents also prevent the glue from sticking to the tube). These solvents either evaporate into the air when you push them out of the tube, or they are absorbed by the surface on which you apply them.

Once the solvent is vaporized, the molecules of polystyrene lock together and form a very strong chemical bond. The unpleasant smell dissipates when dry because of the vaporized solvents.

What are the different types of plastics

There are different types of plastics, and you need to understand their nature before you start looking for the appropriate glue. There are plastics with the recycling symbol and they are marked with “PS” or “6.”

These polystyrene plastics are used for simple and basic level items, including plastic bowls, disposable cutlery and fashion bags. The best glue for this type of plastic is poly cement glue.
Other types of plastic, such as drainpipes, are used for commercial or industrial purposes. Some special kinds of plastic are used to make different types of medical equipment and even bulletproof vests. Biocompatible adhesives are used for such plastics.

  • Glue for hard plastic

High density or hard plastics are used to make containers, buckets or crates. These plastics are polypropylene or polyethylene. Your regular white or wood glue, or common adhesives, are not going to work with these materials.

A cyanoacrylate adhesive is ideal here because it is resistant to water and it dries fast and clear. This glue is best for automotive plastic, eyeglass frame plastic and laptop plastic. You can also use this to fix fridge plastic.

  • Glue for clear plastic

The glue for clear or flexible plastics are frequently used in households, and you can apply them on toys or shoes, etc. Vinyl adhesives are ideal for working with these materials because they are waterproof and they won’t break with UV exposure.

This glue is suitable for nylon plastic, plastic toys, plastic models and miniatures, as well as foam to plastic applications.

Gluing plastic to plastic

To glue plastic with plastic, make sure that you get rid of any grease from the surfaces that you want to join. You can do so with the help of soap or isopropyl alcohol. For minimizing the oil residue, you need to avoid touching the surfaces after they are washed.

Next, with the help of sandpaper, you need to create a rough surface for the glue to bond effectively. Emery cloth or steel wool will work, too. Now prepare your glue and apply it using a needle tip or small brush. Then hold the surfaces tightly together until dry.

Gluing plastic to other materials

Depending on your projects, you will also have to work with other materials in combination with plastic. Here are a few of the most commonly used materials in combination with plastics and the glue that will work the best for each combination.

Here, an epoxy plastic bonder will produce the best results. Epoxies work better with ABS, PVC, Plexiglas, polycarbonate and polystyrene. But epoxies do have a slow drying time.

  • Glue for plastic to wood

Super glue is going to work wonders here due to its cyanoacrylate content. It has a very speedy drying time, and it is not runny, which means that you can apply it with ease. It is resistant to water and will hold for a long time.

Vinyl adhesive is the best choice – it is a clear liquid bond that you can use for flexible or clear plastics with fabric. It is water and UV proof and works outdoors as well.

A butyl formula based glue makes it better than standard super glue to work on smooth surfaces. Make sure that you sand the plastic surface before you apply the glue, and hold the two surfaces together tightly for optimal results. This glue is good for acrylic plastic.

Tips for gluing plastic

Make sure that you thoroughly clean the plastic surface prior to applying the glue. You can wash the surface with soap or any plastic-specific cleaner. You can also use isopropyl alcohol for cleaning purposes.

It is better to create a rough surface before you apply the glue. You can do this by sanding it using sandpaper (120 to 240 grits). An emery cloth or steel wool can also work. But keep in mind that you only need to rub it briefly.

For better precision, you need to use small application tools. A needle tip or a small paintbrush will be quite handy.

When using 2-part adhesives or epoxies, you need to be very precise with the blending ratio for ideal results; follow the instructions carefully.

You can use clamps, tape or elastics to hold the surfaces together; curing times for different glues can range from a few seconds to 24 hours.

Make sure to get rid of any spillage or excess glue with the help of isopropyl or denatured alcohol. Spirits are also handy in such scenarios.
