The launch forms a key part of the
company’s latest ‘Bonded for Life’ campaign, which highlights how its adhesive innovations are helping manufacturers meet growing demands for safer, smaller and more sophisticated medical devices, while accelerating production and navigating increasingly complex regulatory landscapes. “Our medical adhesives save more than
just time,” said Paul Marshall, marketing head for UK, Ireland and Nordics at Henkel.
“They give manufacturers the flexibility to design more advanced devices, improve production efficiency and meet the rigorous safety and performance standards required in today’s healthcare environment. “Ultimately, by ensuring strong, reliable bonds in critical medical applications, our solutions can help protect patient well-being and support better clinical outcomes.” To support these new products, LOCTITE is also releasing dedicated whitepapers that explore the application, materials and the performance benefits of these adhesives in modern medical device manufacturing.
The study focused on the long-term
performance of adhesive connections under demanding temperature and humidity storage conditions, reinforcing the role of adhesives in enabling efficient mass production of miniLEDs and future microLED applications. Building on its 2024 feasibility study, which
proved adhesives capable of reliably establishing electrical and mechanical miniLED connections, DELO has now examined their durability over extended test periods. Using stamping to dispense precise adhesive volumes onto structured test boards, single and arrayed miniLEDs were cured with a thermode process at 180˚C. The connections were then subjected to extended storage tests of up to 500 hours at 85˚C/85% relative humidity and at 120˚C.
According to the company, the evaluation included light-on validation, U-I characteristic measurements, and die-shear testing. Results showed stable mechanical strength and excellent electrical performance over time, closely matching the specifications from the LED data sheets, even after prolonged exposure to elevated heat. A critical test scenario combined both heat and humidity, which typically challenges solder- based connections. Even under the most demanding conditions, directional conductive adhesives remained reliable, underscoring their suitability as a robust connection technology for next-generation displays. “These results show that directional
conductive adhesives are not only technically feasible for miniLEDs but also reliable in long-term conditions that realistically reflect industrial environments,” said Maximilian Baum, director Product Management Consumer
To help, Intertronics has released the ’What is a medical adhesive?’whitepaper, which explores six key characteristics that determine adhesive suitability for medical devices: adhesion, biocompatibility, sterilisation, compliance, patient contact duration, and process validation and QA. The paper focuses on adhesives for device
assembly, rather than those used therapeutically in the body or to secure devices to a patient’s skin. It explains the importance of ISO 10993 biocompatibility testing, compatibility with sterilisation methods as part of design, and
robust repeatable processes to ensure validated, reliable and compliant device assembly. “Medical device assembly is high precision,
high compliance, and high consequence. Adhesive selection and processing can be a fundamental contributor to patient safety and regulatory approval,” explained Peter Swanson, chair at Intertronics and author of the white paper. “By carefully considering each of the six
key characteristics, manufacturers can ensure that their adhesive not only performs well mechanically but also meets the requirements for biocompatibility, sterilisation and compliance. Getting these decisions right from the start helps accelerate approval timelines, reduce the risk of revalidation, and ultimately deliver safer, more effective, medical devices.” The whitepaper can be found here:
