Brass is an alloy of zinc and copper, and is non-magnetic, corrosion-resistant, and malleable. Various adhesives can be used to bond brass to plastic, including cyanoacrylate adhesives (also known as instant adhesives or super glue), epoxy, and anaerobic adhesives. The best adhesive for the job will depend on the specific materials being used, the surface area available, and the desired qualities of the adhesive, such as curing time and bond strength.

Roughen the brass surface with sandpaper to improve adhesion
When working with brass, it is important to wear a dust mask and nitrile gloves to avoid inhaling metal dust or making contact with the skin. Before using sandpaper on a brass surface, it is crucial to clean the brass thoroughly with a degreasing agent or a mild soap to remove any grease, dirt, tarnish, or oxidation. This step ensures that contaminants do not impede the sanding process or cause scratches on the surface.
Once the brass surface is clean and dry, you can start the sanding process. It is recommended to start with fine-grained sandpaper, typically in the range of 220 to 400 grit, to lightly sand the surface and create a rough texture. This process helps improve adhesion by providing a better surface for the adhesive to grip onto. If you are aiming for a very smooth finish, you can use sandpaper with a finer grit, such as 600 grit or higher. However, keep in mind that brass tends to become a little sticky when moving up to finer grits.
When sanding, use a wooden backer to keep flat parts flat and ensure an even finish. You can also use a buffing wheel, but it requires some skill as it can quickly round over parts that you don't want to be rounded. If you are working with intricate or irregular shapes, a foam backer can help you reach those areas more effectively.
After sanding, it is essential to wipe the brass surface with a tack cloth to remove any remaining dust. This step ensures that the dust does not interfere with the adhesion process or create an uneven finish. Once the surface is clean and roughened, you can proceed with the chosen adhesive, following the manufacturer's instructions for the best results.
Additionally, consider using a primer specifically designed for metals to further enhance adhesion and reduce the chances of paint flaking if you plan to paint the brass surface. Allow the primer to dry completely before applying paint or any other finish. By following these steps and properly roughening the brass surface with sandpaper, you will achieve better adhesion when bonding brass to plastic.

Use superglue for a strong, precise bond
Superglue is a great option for bonding brass to plastic. It is a versatile adhesive that can effectively bond metal to plastic and a variety of other materials. If you're working with two flat surfaces, super glue is the best way to go.
When using superglue, it is important to ensure that the surfaces are smooth, clean, and close-fitting. Prepare your work area and mark the areas to be glued. You should also consider whether your project will be indoors or outdoors and if the surfaces will be exposed to water. Always read the manufacturer's instructions to ensure the product is compatible with both plastic and metal.
Loctite offers a range of super glues suitable for bonding brass to plastic. For instance, the Loctite Super Glue Liquid Precision is ideal for strong, precise bonding and comes with a specially designed nozzle for added precision. It dries transparent, making it perfect for invisible repairs. If you're working with a larger surface area, the Loctite Super Glue Liquid Brush On is a good choice. It comes with a brush applicator, making it quick and easy to cover a large surface.
While super glue is a great option for bonding brass to plastic, it may not be the best choice if you're looking for a very strong bond. In that case, you might want to consider other adhesives like epoxy or a two-part epoxy for the strongest bonds. However, if you're looking for a quick, easy, and versatile solution, super glue is the way to go.

Anaerobic adhesives cure faster on brass than on steel
There are various methods for bonding brass to plastic, including the use of rubber-based adhesives, J-B Weld, and Duco cement. However, the focus here is on anaerobic adhesives and why they cure faster on brass than on steel.
Anaerobic adhesives are one-part adhesives that cure in the absence of oxygen and the presence of metal. They are often used for structural bonds with materials such as metals and glass and, to a lesser extent, wood and plastic. The cure speed of anaerobic adhesives is influenced by the choice of activator, temperature, and the reactivity of the metal surface.
Brass is an alloy of zinc and copper known for its non-magnetic, corrosion-resistant, and malleable properties. It is one of the most reactive metals, which plays a crucial role in the curing process of anaerobic adhesives. When these adhesives come into contact with a highly reactive metal like brass, the curing mechanism is accelerated.
On the other hand, steel is a less reactive metal compared to brass. At room temperature, a general-purpose thread locker anaerobic adhesive would typically take 10-15 minutes to cure on steel, while the curing process on brass would be significantly faster due to its higher reactivity.
The increased reactivity of brass shortens the curing time required for anaerobic adhesives. This property of brass can be advantageous in applications where faster curing is desired, such as in threadlocking, thread sealing, form-in-place gaskets, and retaining compounds.
