What is the main difference between a bonded and a non-bonded adhesive?

• A. Bonded adhesives dry faster
• B. Bonded adhesives create a permanent bond while non-bonded can be removed
• C. Bonded adhesives are stronger
• D. Bonded adhesives are more expensive

Answer: (B)

The key distinction between bonded and non-bonded adhesives lies in the nature of the bond they create. Bonded adhesives are designed to form a permanent bond between surfaces, meaning that once they set, the materials are tightly held together and cannot be easily separated without damaging either the adhesive or the materials involved. This permanence is crucial in applications where strength and durability are important, such as in structural or load-bearing assemblies. In contrast, non-bonded adhesives may allow for removal without causing significant damage to the materials. This characteristic can be beneficial in applications requiring changes or maintenance, as users can detach items without compromising their integrity. For example, temporary bonds might be desirable in some woodworking projects where future adjustments are anticipated. While other choices address aspects such as speed, strength, and cost, the essence of the main difference is centered on the permanence of the bond established by bonded adhesives compared to the more transient nature of non-bonded options.
