Bond strength is a comprehensive measure of an adhesive's ability to hold two substrates together. It measures the resistance to separation and is affected by various factors, including the type of adhesive used, the bonding surface preparation, and the bonding process.

To fully understand the bond strength of an adhesive, it's necessary to understand the types of stress imparted on adhesive joints. The most common stresses include shear, peel, tensile, compression, and cleavage.

All these terms relate to the integrity of adhesive joints while measuring different strength aspects of the adhesive's performance. Below is a summary of each.

Shear strength measures an adhesive's resistance to forces parallel to the bonded surfaces. It represents the adhesive's ability to withstand pull directed across the adhesive, forcing the substrates to slide over each other. It is commonly tested by subjecting the bonded materials to a force applied parallel to the adhesive joint. A strong adhesive joint should exhibit both high bond and shear strength.

In the worlds of construction, manufacturing, and DIY projects, sealants and adhesives play an essential and pivotal role in ensuring structural integrity, preventing leaks, and bonding materials together. However, navigating the sea of sealant and adhesive terminology can be daunting. Understanding the terminology related to sealants and adhesives is essential for making informed decisions. To help you through the process, we have provided a comprehensive guide to some of this field’s most common terms and concepts.

 
The choice to join metals typically depends on factors such as the type of metal(s) being joined, load-bearing capacity and durability requirements, disassembly and repair factors, and other application requirements. The common ways to join metals include welding, mechanical fasteners, or adhesives.
