Identify technical specification and draw a test plan for a targeted application

Debonding on demand is a hot topic for the adhesive industry and the production of multimaterials, especially to address and of life or repair. However, the widespread use of adhesives, made necessary in the early years to be able to separate bonded parts, which led to the development of debonding process or protocols, based on mechanical tools, heat, or solvents. These “old-fashioned” techniques must always be considered in the 1^st stage of the definition of a debonding system, since it may be more efficient and more reliable, as far as the durability of the bonded joint is concerned, to keep the standard adhesive and debond it with one of these “simple” processes.

In addition, several technological approaches are available for the development of debondable adhesives. From modified resins, with special synthesis processes, to specific formulations with debonding fillers. These bonding materials can show reversible or non reversible debonding, depending on the technology used for the disbonding.

Last but not least, debonding on demand needs to be seen as one part of a larger picture, with the final objective of debonding in mind. Is it for repair or for end of life? Who will do the debonding and where? As debonding is often implemented in the framework of a closed loop manufacturing strategy, these aspects are crucial to make the debonding operations economically and environmentally sound.

Selecting a suitable debonding-on-demand system for a targeted application involves several key considerations to ensure that the system meets both performance and functional requirements. The definition of these requirements is needed beforehand as well as the test plan to assess the conformance of the developed debonding on demand systems. The following course details how to break this down into various key components.
