DELO Launches Five New IBOA-Free Medical Adhesives

Enhanced biocompatibility meets proven performance for next-generation wearable medical devices

Medical device manufacturers face increasing challenges balancing high-performance bonding with strict biocompatibility requirements. Traditional adhesives often contain skin-sensitizing substances that limit their use in direct patient contact applications.

DELO Industrial Adhesives has significantly expanded its medical electronics portfolio with five new IBOA-free medical adhesives. The high-tech manufacturer adapted proven flagship products from semiconductor and consumer electronics for biocompatible adhesives applications.

What makes these medical device adhesives special?

DELO's new TPO-free adhesives portfolio combines decades of miniaturization expertise with enhanced biocompatibility features. All products undergo rigorous cytotoxicity testing according to DIN EN ISO 10993-5 standards.


Leading the portfolio is DELO PHOTOBOND MG4202, specifically designed for structural bonds in wearables. This skin-safe adhesive offers remarkable fast curing capabilities - just one second at 1000 mW/cm² LED intensity. The colorless adhesive operates across temperatures from -40°C to +125°C.


Your key advantages with DELO's IBOA-free medical adhesives:
  • Complete IBOA and TPO-free formulation for enhanced biocompatibility
  • Fast curing in just one second for efficient manufacturing processes
  • H317-free formulation eliminates skin-sensitizing substances
  • RoHS compliant adhesives meeting all regulatory requirements
  • Temperature range -40°C to +125°C for diverse applications
     

Comprehensive solution portfolio for medical electronics

The complete portfolio includes five specialized variants for different medical electronics bonding applications. DELO PHOTOBOND MG4191 serves as a versatile, multi-purpose solution with high strength and flexibility. This lower-viscosity modification offers excellent water resistance.


Three additional specialized variants complete the range:
  • DELO PHOTOBOND MG4094 - fluorescent properties for visual process control
  • DELO PHOTOBOND MG4186 - peel resistance with high reliability
  • DELO PHOTOBOND MG4164 - blue fluorescence with sealing capabilities

Perfect for wearable medical devices

The new adhesives for glucose monitoring sensors complement DELO's existing medical portfolio, including the hydrophobic DELO PHOTOBOND MG4047 for potting applications. These solutions protect underlying electronics from moisture and sweat in wearable medical devices.
