DELO Industrial Adhesives announced on Apr. 16 the expansion of its medical electronics portfolio with five new adhesives that are free from IBOA and TPO. The company has adapted successful products from its semiconductor and consumer electronics divisions to meet the needs of medical device manufacturers, focusing on enhanced biocompatibility.
The development is significant as it addresses the increasing overlap between medical and consumer electronics, especially in areas such as wearable devices, biosensors, and advanced monitoring systems where both performance and patient safety are important.
The leading product in this range is DELO PHOTOBOND MG4202, which is designed for structural bonding in wearables. According to DELO, this adhesive cures quickly—within one second at a specified LED intensity—and operates across a wide temperature range. Another product, DELO PHOTOBOND MG4191, is described as a versatile solution that does not contain skin-sensitising substances while maintaining strength and flexibility. Additional variants include adhesives with features such as fluorescence for process control or high peel resistance.
All products in the expanded portfolio have undergone biocompatibility testing according to DIN EN ISO 10993-5 standards for cytotoxicity and comply with RoHS Directive 2015/863/EU requirements. They are available in standard cartridge sizes intended for ease of use by manufacturers.
Günther Witek, product manager for medical electronics at DELO, said: “This portfolio expansion represents the perfect convergence of our proven semiconductor and consumer electronics expertise with the growing demands of medical device manufacturers. By adapting our most successful adhesive technologies for biocompatible applications, we’re enabling our medical customers to benefit from decades of miniaturisation and manufacturing excellence.”
The company noted that these new adhesives complement existing offerings such as DELO PHOTOBOND MG4047—a low-viscosity solution used in potting applications like glucose monitoring sensors—to protect sensitive electronic components from moisture exposure.
