Advantages of Adhesive Bonding

Adhesives have several advantages over other types of bonding, like welding, or even using screws or nails.

• Adhesives distribute the weight between two substrates more evenly, reducing stress on joints.

• Adhesives are invisible, which means you get a nice, clean seamless line where the materials join.

• Adhesives form a seal, as well as a bond, which protects the joint from corrosion.

• Other hot melt adhesives can join irregularly shaped surfaces, quickly and easily bonding the substrates.

• Assembly line operations are much easier, as there is less need for customization in the bonding process.

History of Hot Melt Adhesives

Archeologists have found evidence of humans using adhesives over 6000 years ago. The Ancient Egyptians used a form of glue to seal the wooden caskets of the pharaohs. However, modern adhesive technology did not begin to evolve until about 100 years ago.

A scientist invented thermoplastic glue, today is known as hot melt, in 1940. The scientists wanted something that would seal cereal boxes and stop them from popping open before getting to the consumer.
