But depending on the instance at hand, the quality and bonding strength of the glue required can fluctuate greatly. In today’s article, we will give a rundown of the best glue for plastic to metal that we have tested. As usual, we will also provide you with a buying guide and FAQs section for general advice and tips. Let’s get started!
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.
