DELO adds to its medical portfolio with new adhesive for biosensors

Based on a long-proven consumer electronics adhesive featuring low-temperature curing and drop resistance, this adhesive expands upon its capabilities with non-cytotoxicity, thus meeting the standards (DIN EN ISO 10993-5) necessary to classify it as a medical-grade adhesive.

DELO MONOPOX MG3727 is tailored ideally for use in the assembly of
biosensors, including ECG/EKG electrodes. As stainless steel is often central to the construction of such equipment, DELO ensured that the new adhesive performs well with this substrate material, testing at a compression shear strength of 11MPa.

This one-component, solvent-free and humidity-resistant adhesive features a low Young’s modulus of 160MPa, making it
resistant to cracking under sudden impact, such as if a sensor falls to the ground. 

A low glass transition temperature of -52°C helps the adhesive retain its properties across the range of temperatures at which a sensor may be utilised.

DELO MONOPOX MG3727 takes 10 minutes fully to cure via
a low heat of 90°C, making it optimal for temperature-sensitive substrates. 

With a viscosity of 30,000mPa, it can be easily applied via needle dispensing for optimal production efficiency. Blue fluorescence allows for increased process control of dispensing accuracy.

“This is just one of many medical-grade materials we have planned,” says Günther
Witek, Product Manager For Medical Electronics at DELO. 

"And, more importantly, we will bring our semicon manufacturing, miniaturisation, and equipment expertise to market, enabling our customers to produce astonishing new products.”

DELO Industrial Adhesives specialises in advanced adhesives and materials for manufacturing in the automotive, consumer electronics, and semiconductor industries, looking to expand within the field of medical electronics.
