The Basics of Adhesives for Metal

Adhesives are materials that bond two surfaces together. They come in various forms such as liquids, pastes, tapes and films. Adhesives for metal applications are specifically designed to bond metal surfaces to each other or to other surfaces like plastics, glass, ceramics, wood, and composites. Different types of adhesives have different properties and advantages depending on the application.

Why Adhesives are Essential for Metal Applications

Adhesives are essential for metal applications because they provide a strong and durable bond that can withstand high stress and vibrations. Unlike mechanical fasteners such as screws, bolts or rivets, adhesives distribute the load evenly across the entire bonding area. This helps to reduce stress concentrations that can lead to fatigue failure. Adhesives also eliminate the need for drilling holes or welding, which can weaken the metal and create corrosion-prone areas. Adhesives for metal bonding are also ideal for joining dissimilar metals or non-metallic materials that cannot be welded or brazed.
