What is the strongest most durable glue?

There are several types of strong and durable glues available, each with its own specific applications. Some of the strongest and most durable glues include:

1. Epoxy: Epoxy adhesives are known for their exceptional strength and durability. They consist of two components that need to be mixed together before application. Once cured, epoxy forms a strong bond that can withstand high temperatures, chemicals, and heavy loads.

2. Cyanoacrylate (Super Glue): Cyanoacrylate adhesives, commonly known as super glue, are known for their fast bonding and high strength. They form a strong bond between various materials, including plastics, metals, ceramics, and rubber.

3. Polyurethane: Polyurethane adhesives are highly versatile and offer excellent bonding strength. They are resistant to water, chemicals, and impact, making them suitable for various applications, including woodworking, construction, and automotive repairs.

4. Structural Acrylic: Structural acrylic adhesives are designed to provide high strength and durability. They are commonly used in bonding metals, plastics, and composites. These adhesives can withstand extreme temperatures, vibrations, and impact.

5. Silicone: Silicone adhesives offer excellent durability and flexibility. They are resistant to water, heat, and UV radiation, making them suitable for sealing and bonding applications in various industries.

It's important to note that the strength and durability of a glue depend on the specific materials being bonded and the intended application. It's always recommended to follow the manufacturer's instructions and choose a glue that is suitable for your specific needs.
