This article will show you how to glue plastic to metal. Choosing the right adhesive is key. We’ll cover a variety of situations that you may encounter.
There are several common adhesives used for bonding metal to plastic, each with advantages for specific projects. We’ll cover these in detail to help you choose the right glue for your repair.
Here are some primary considerations:
Let’s review three of the most common methods to bond metal to plastic.
Super glue is the easiest method and will work in many situations. Here’s how to use it:
Plastic bonder is very similar to super glue with the addition of a primer or activator. It is a great way to glue metal to plastic when using hard-to-bond materials.
Simply apply activator to each surface, allow it to dry for 60 seconds, then apply the glue to one surface as you would with other glues.
Epoxy is a two-part adhesive that must be mixed before using it. Many epoxies come in a dual syringe dispenser that makes it easy to measure out equal parts of the resin and hardener onto a disposable surface. The two materials should be thoroughly mixed and then applied as you would with super glue. Check the label as to setting time because epoxies vary, and you have limited time to work with it before it hardens.
Some types of plastic are particularly challenging to bond to with ordinary adhesives. Polypropylene (PE), polyethylene (PP), and Teflon are among them. If you need to bond to these or similar materials, you will need a plastic bonding system or specialty glue.
For quick and easy repairs to smaller items, try LePage Super Glue Gel Control. This handy adhesive dries transparent in seconds and holds stronger than many similar glues. It will bond to metal, plastic, wood, leather, and more. You’ll love the precision dispenser.
If you need a glue that can handle those hard-to-bond surfaces like polypropylene, polyethylene, or Teflon, LePage Super Glue All Plastics is the best choice. No mixing is required, simply apply the primer/activator, wait one minute, and apply the glue. It’s resistant to moisture, most solvents, and temperature extremes.
When epoxy is called for, we recommend LePage Epoxy Gel. It’s an excellent choice because it won’t drip or run, sets in about six minutes, and bonds to metal, glass, ceramics, most plastics, and even masonry materials. It dries to a very resilient, machinable finish that can be sanded and painted.
