[**DELO Industrial Adhesives**](https://www.delo-adhesives.com/?ref=med-techinsights.com) has expanded its medical electronics portfolio with five new IBOA- and TPO-free adhesives. The high-tech manufacturer has adapted successful flagship products from its semiconductor and consumer electronics divisions for medical device applications, delivering enhanced biocompatibility features.

Leading the new portfolio is DELO PHOTOBOND MG4202, designed for structural bonds such as housing bonding in wearables. DELO says this solvent-free, IBOA-free adhesive offers fast curing capabilities, just one second at 1000 mW/cm² LED intensity at 400 nm with 100 μm layer thickness. The colourless adhesive operates across a temperature range of -40°C to +125°C.

DELO PHOTOBOND MG4191 serves as a versatile, multi-purpose solution that is completely free of skin-sensitising substances (H317-free) while maintaining high strength and flexibility. This lower-viscosity modification offers good water resistance and flow-resistant properties, making it ideal for various medical device applications.

The complete portfolio includes three additional specialised variants: DELO PHOTOBOND MG4094 provides fluorescent properties for visual process control, DELO PHOTOBOND MG4186 delivers peel resistance with high reliability, and DELO PHOTOBOND MG4164 combines blue fluorescence with sealing capabilities for FIPG and CIPG applications.

The company says that all products meet stringent medical industry requirements, including biocompatibility testing according to DIN EN ISO 10993-5 for cytotoxicity. They comply with RoHS Directive 2015/863/EU and are available in convenient 30cc cartridges.

“This portfolio expansion represents the perfect convergence of our proven semiconductor and consumer electronics expertise with the growing demands of medical device manufacturers,” said Günther Witek, product manager for medical electronics at DELO. “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 new adhesives complement DELO’s existing medical portfolio, including the low-viscosity, hydrophobic DELO PHOTOBOND MG4047 for potting applications in glucose monitoring sensors and other wearables, protecting underlying electronics from moisture and sweat.

The company says that together, these solutions address the increasing convergence of medical and consumer electronics industries, particularly in wearable medical devices, biosensors, and advanced monitoring systems where both performance and patient safety are critical.
