Enabling reliable and repairable digital technologies

Adhesives and sealants are integral to digital technologies, from semiconductor and smartphone manufacturing to device assembly, use and repair. They enable miniaturisation, make possible advanced materials, manage heat, provide waterproofing and improve durability. By supporting disassembly, they help extend product life, improve safety, reduce waste, and make electronic systems more sustainable. Adhesives and sealants encourage innovation, while also contributing to resource efficiency and circularity.

The technical applications of adhesives and sealants, and the benefits afforded

Adhesives and sealants are used throughout electronic devices, including tablets, wearables, audio equipment, and automotive electronics systems. They are applied at multiple levels of assembly, from internal micro-components to external casings.

In electronic devices, adhesives are used to assemble housings, secure components and protect sensitive parts where traditional fastening methods are not suitable.

They also support the miniaturisation of electronic systems by enabling the integration of small, lightweight components in applications where space is limited and there is minimal margin for error. For example, they are used to fix microchips, sensors, and camera modules onto circuit boards where mechanical fasteners would be too large or would add stress to fragile components.

Adhesives and sealants and circularity

Adhesives are also used to enable repair, particularly in components such as mobile phone batteries. Debondable and stretch-release adhesives, for instance, allow components to be removed safely and efficiently. This supports repair, replacement and maintenance, in line with EU policies such as the Right to Repair Directive and repairability scoring for smartphones and tablets.

Adhesive technology is relevant for sustainability and resource use. Enabling battery replacement extends device lifespan and reduces electronic waste. It also supports compliance with end-of-life frameworks such as the WEEE Directive by facilitating disassembly and material recovery.
