Types of metal glue
Choosing the best glue for metal is essential to a strong fit. Metal glues generally fall into three types: epoxy, polyurethane, and super glues.
Epoxy adhesives are high-performance adhesives often used in carpentry and woodworking or for specialized creative uses like making costume jewelry. These practices include not only wood, but also metal in some instances such as handrails, table legs or doorhandles. Epoxies come in different types with different properties: flexible or rigid, transparent or opaque, fast or slow setting. They also offer high resistance to heat and chemicals.
The best epoxy for metal is Loctite Epoxy Metal/Concrete, a two-part system consisting of an epoxy resin and a hardener. The resin and hardener are combined to create a durable, high-strength bond that dries in minutes and can be used for repairing, filling, and rebuilding all metal and concrete surfaces.
Polyurethanes are also commonly used with metal. Polyurethanes are water-resistant and UV-resistant and set quickly without being brittle. Once cured, they can be sanded, stained, and painted. That makes them great for many jobs around the house, including repairing flooring or finished carpentry like cabinets or tables.
A quality exterior construction adhesive should be a polyurethane-based, moisture-curing adhesive to create stronger bonds than ordinary construction adhesives. Like many polyurethanes, it works on metal across a wide range of temperatures, making it the best metal glue for outdoor use.
Super glues are high-performance industrial adhesives that are perfect for almost all household fixes. Most bond well with metal, as well as fabrics, wood, and plastics, making them useful in joining or repairing car parts, ornaments, small appliances, and many other daily items.
For superior bond of metals, Loctite Super Glue Liquid is reliable and fast. It’s strong and simple to use; weather and moisture resistant, it sets in seconds, requiring no clamping, and it applies easily.
