Gorilla 2 Part Epoxy

Gorilla 2 Part Epoxy

When comes to the best glue for bonding plastic to metal, various epoxies are best to use. Epoxies generally consist of two components, a resin and a hardener. These are kept in separate bottles or compartments in a syringe.
When the two components mix together, they create a thermosetting chemical reaction that causes the mixture to harden. These tend to have great chemical and solvent resistance, water resistance, and heat resistance too.
Our number one top pick for the best plastic to metal glue is Gorilla 2 Part Epoxy. There are a few key features to be aware of.

  • Permanent bond
  • High tensile strength
  • Ideal for repairs and gap filling

Gorilla 2 part epoxy glue is ideal for bonding metal to plastic, as it can be used for a wide variety of materials. It works for plastic, metal, wood, ceramic, tile, fiberglass, and more.
This glue sets in about 5 minutes, but takes about 24 hours to cure. This allows for plenty of time to work with it and to position pieces before the glue hardens.
The resin and hardener are each contained in a separate compartment of a syringe, thus keeping them apart prior to use.
The syringe features 1 push stopper, thus allowing the components to be evenly dispensed at once. However, do remember that some mixing is required before the glue can be applied to any surface.
This glue dries clear for easy finishing. It also forms a very durable bond that is ideal for repairs, for crafts, and more. Moreover, once cured, this glue is resistant to solvents, heat, and water.

Epoxy

Epoxy is probably your best bet to go with for bonding plastic to metal. The reason for this is because epoxy forms an extremely strong bond with very high tensile strength and impact resistance.
For the most part, it is also extremely resistant to most common solvents, to chemicals, to water, and to heat. Although epoxy may take up to 24 hours to cure, once it is totally cured, it forms a rather permanent bond that is near impossible to remove.
Epoxy can come in a tube or syringe, and it can come in the form of putty as well. For bonding plastic to metal, the syringe variety is probably best.

Cyanoacrylates

This is the technical term for super glue, which you are probably familiar with. Super glue is also known as instant glue due to the fact that it tends to set very quickly. Depending on the exact kind you get, the glue may totally set and cure within minutes or even seconds.
Now, super glue does not have the best sheer strength and it does not work too well with smooth surfaces.
However, when it comes to rough surfaces, it does have high tensile strength and impact resistance. Moreover, if you get the right kind, it can also be very resistant to water, heat, and most solvents. You may also like how this type of glue usually always dries clear.

Glue For Plastic to Metal – Buying Guide

Keep multi-material bonding in mind when making your purchase

One of the first things that you should keep in mind when buying glue for bonding hard materials is how widely applicable it is. Since the bonding strength, you are looking for needs to be strong enough to bond two hard materials, the glue should work effectively with multiple materials like wood, glass, metal, etc. The bond needs to be strong enough to handle drilling, filing and other extra stress – fresh off the bonding process. But sometimes, depending on your requirements, particular selections need to be made based on relative surface energy, elastic modulus and thermal expansion of the bonding materials. Plastics require different bonding agents based on HSE (High Surface Energy) or LSE (Low Surface Energy).

Common types of glues used for plastic to metal bonding

The most common types of glues available on the market for public purchase are tube-based glue and two-part epoxy putties. While both types are effective, the mixture based epoxy putties generally have more bonding strength than the tube based-glue, unless the former is industrial grade. Tube-based glue are best for small and intricate repairs, as the nozzle is generally small enough to reach small cracks and gaps. These types of glue are most popular for crafts and small-item repair, like miniature models. These types of glue are comparatively easy to get off your skin. The putty based adhesives for plastic to metal are more commonly used for large repairs and handymen work. The application process needs more care, but the bond is capable of withstanding rough weather and extreme temperatures. Compared to tube-based glue, putty-based glue are more sticky and difficult to get off skin or clothes. Base your purchase on what your actual needs are.

How to pre-prepare surface for bonding with professional-grade glue

With some putty based adhesives, preparing the mixture alone is not enough. You also need to prepare the surfaces that are going to be bonded so that the process is done properly and effectively. This basically boils down to cleaning the surface properly and sometimes varnishing and dusting as well. Cleaning the surface with sandpaper or steel wool is very effective and is done by professional handymen. But never the less, it is advisable to follow the instruction manual as closely as possible.

FAQ

What are metal glues and how many types are there?

Metal glue are special glue with extra strength made for bonding hard materials. In the glue industry, adhesives are categorized under 3 major categories: epoxy adhesives, polyurethanes, and superglues. Out of these three, superglue are the most commonly used by the general public.

What is a control applicator?

A control applicator might sound sophisticated but is actually a very simple gadget. A control applicator is used with tube-based glue and allows for extra precision and control when squeezing the tube.

How to avoid skin spills?

When using superglue for repairs, no matter what size, it is highly advisable to use gloves. You don’t need to buy heavy-duty gloves for easy applications like crafts and jewelry repair. Simple, disposable, plastic gloves are more than enough to avoid skin spills.
