Buying Guide
There are only two main things you need to think about before you buy a glue for plastic to metal. On this list, all the glues will work with plastic and metal, so that is not one of them. What you need to work out is if you need a heavy-duty glue and how much glue you’re going to need.
Glue Strength
Although all of the glues on this list are strong in their own regard, some are stronger than others. If you are working on a project with particularly heavy materials, you need a stronger glue. This is the case for heavy plastic objects and sheets of metal.
Before buying a glue, make sure it can bear the load of what you need it to take. On this list, we feature two very strong glues. You can find these in the Heavy-Duty and Industrial Strength sections.
If you’re only working with light materials, then glue strength won’t matter as much. All of the glues on this list will easily cope with light materials. That means you could select any you want for your project.
Glue Amount
Some of the glues on this list are specially made for craft projects. Due to how small these projects are, the glues come in smaller amounts. For example, the Loctite glue on this list is only 0.47 ounces. While this works for small projects, that will not be enough glue for anything larger.
When considering which glue to buy, estimate how much glue you are going to need. The larger your project, the more glue you will need. Due to this, pay close attention to all of the glue amounts listed in each section.
Conclusion
If you were looking for the best glue for plastic to metal, this list was the right place for you. We recommend these five glues based on their strength, durability, and drying time. Each of the glues on this list works fantastically. However, be sure to use the buying guide before committing to a glue. The best glue for your project will vary!
