DELO Industrial Adhesives has developed a new medical grade adhesive, DELO MONOPOX MG3727, specially tailored for use in the assembly of biosensors, including ECG/EKG electrodes.
Based on a long proven consumer electronics adhesive featuring low temperature curing and drop resistance, DELO MONOPOX MG3727 meets the standards of DIN EN ISO 10993-5 necessary to classify it as a medical grade adhesive.
This one component, solvent-free and humidity resistant adhesive features a low Young’s modulus of 160 MPa, 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 temperature where a sensor may be utilised.
DELO MONOPOX MG3727 takes ten minutes to fully cure via a low heat of 90°C, making it optimal for temperature sensitive substrates. With a viscosity of 30,000 MPas, it can be easily applied via needle dispensing for optimal production efficiency. Blue fluorescence in the material 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. "More importantly, we will bring our semicon manufacturing, miniaturisation, and equipment expertise to market, enabling our customers to produce astonishing new products.”
