Biocompatible UV curable adhesive formulated for TPU bonding
UV17Med is a low viscosity, UV curable system with an affinity for bonding thermoplastic urethanes.
Non-Cytotoxic Epoxy for Bonding, Sealing, Coating and Encapsulating
Master Bond UV17Med is a one part, no mix, UV curable system. It was specially formulated to provide excellent adhesion to many TPUs (thermoplastic polyurethanes), which are widely recognised as challenging substrates for bonding. This compound provides very good toughness with a high elongation of 50-60%. UV17Med passes stringent ISO 10993-5 cytotoxicity standards.
UV17Med cures in 10-30 seconds when exposed to a UV light source emitting at a wavelength of 320-365 nm with an energy output of 20-40 milliwatts/cm2. It is recommended that one of the surfaces to be bonded is transparent, without UV blocking agents. This allows the light to penetrate the substrate’s surface with no shadows. It is a flowable system that features a low viscosity of 500-3,000 cps, a tensile modulus measuring between 30,000-50,000 psi, and a service temperature range from -80°F to 250°F.
This non-cytotoxic system is capable of withstanding many chemicals including liquid sterilants, antimicrobial agents, Ethylene Oxide (EtO), e-beam, and gamma radiation. In addition to TPUs, UV17Med bonds well to metals, glass, ceramics and many plastics. The system can be used in medical devices where adhesion to TPUs, along with ISO 10993-5 requirements, are required. It can also be used in non-medical applications where adhesion to thermoplastic urethanes is needed.
We tested several different types of TPU films to see how the T-peel strength of UV17Med performed. Determining the strength requirements for adhesively bonded T-peel joints is essential in meeting stringent reliability requirements of multiple industrial parts. We also tested a generic UV curable adhesive material, as a control. To see how these adhesives compared, and to discover more about this unique Master Bond adhesive, please watch this video now.
