How Do I Choose the Best Metal Adhesive?

There are two main types of metal adhesives: natural and synthetic adhesives. Natural adhesives have simple components and a narrow application range. Synthetic adhesive is the most widely used one, and its main components are: adhesive curing agent, filler, toughening agent, solvent and other additives.

Metal adhesive shear

The external force acts in parallel on the bonding surface, and the force it receives is the shear force. The distribution of shear stress on the bonding surface is relatively uniform. At this time, the bearing capacity of the bonded joint is high.

Metal adhesive stretching

The external force acts vertically on the bonding surface, and the force it receives is the tensile force. The distribution of tensile force on the bonding surface is also relatively uniform. At this time, the bearing capacity of the bonding joint is also high.

Metal adhesive peeling

The direction of the external force acts at a certain angle with the bonding surface, and the force on the bonding surface is the peeling force. The stress distribution is not on the entire bonding surface but on a straight line of the bonding surface. At this time, the bearing capacity of the joint is low and it is easy to be peeled off.

Uneven peeling of metal adhesive

The external force acts vertically on one or both ends of the bonding surface, and the force on the bonding surface is the detachment force. The stress is not distributed on the entire bonding surface, but is concentrated on the edge of one or two ends, and the distribution is uneven. At this time, the bearing capacity of the joint is low and it is easy to split from the end.
