DELO Industrial Adhesives

The world’s strongest adhesives for the world’s most advanced MEMS pressure sensor

DELO is a leading manufacturer of high-tech adhesives and other multifunctional materials as well as adhesive dispensing and curing technology. Its products can be found in most cars worldwide, for example in batteries, electric motors, or sensors. Customers include Bosch, Mercedes-Benz, Osram and Siemens. DELO's headquarters are in Windach, Germany, near Munich, with subsidiaries in China, Japan, Malaysia, Singapore, and USA. The company employs a workforce of 1,080 staff and achieved revenues of almost €230 million in fiscal year 2024.

Withstanding pressure spikes of up to 2,000 bar/ms and static burst levels up to 210 bar while still remaining in contact with liquid media, the Melexis Triphibian family of MEMS pressure sensors offers substantial advantages over competing sensors in durability. This ability, however, cannot be achieved alone. Adhesives with properties that enable ultra-reliable, high-strength fixation play a foundational role in this level of durability.

In 2019, DELO engineered a purpose-built adhesive to break the world record for heaviest weight lifted with an adhesive. Since then, closely related DELO MONOPOX HT mass-market adhesives have been developed for applications with especially high bonding demands. For Melexis’s MEMS sensors, these adhesives prove to be an ideal material pairing.

In testing the feasibility of DELO MONOPOX HT with Triphibian MLX90830, the sensor was able to remain intact through over 1,000 pressure cycles at 200 bar. In addition, the tested adhesive itself demonstrated a high temperature resistance of up to 220 °C as well as excellent media resistance. It surpassed 10,000 h of high-temperature storage without losing its bonding strength.

These results are why Melexis itself recommends using DELO adhesives with its products in its design guide.
